GREENBUG RESISTANCE IN OAT ACCESSIONS FROM DAGESTAN AND CAUCASIAN COUNTRIES
Authors: Radchenko E. E. , Chumakov M. A. , Loskutov I. G. 
Published: October 2019

Background. The breeding of resistant varieties is an effective way to control greenbug Schizaphis graminum Rondani, an economically important pest of oat and other cereals in southern Russia. The insect-host differential interaction necessitates a constant search for new resistance donors.Materials and methods. One hundred and ninety one accessions (mostly landraces) from the Caucasian countries (Armenia, Azerbaijan and Georgia) as well as from the North Caucasus of the Russian Federation (Dagestan) were assessed for greenbug resistance. The Krasnodar (Gulkevichi District) insect population was used in the experiments. The intact plants were uniformly infested with differentaged aphids in the phase of two leaves by shaking insects onto them. When the susceptible control (cv. Borrus) died, the plant damage score was determined using the scale from 0 (no damage) to 10 (91–100% of the leaf surface damaged, plant’s death). The plants with the score of 1–4 points were classified as resistant, 5–8 moderately resistant, and 9–10 susceptible.Results and conclusions. A local oat accession from Georgia (k-4308) was noted for its high insect resistance. Also, heterogeneity of the studied trait was demonstrated by 38 oats forms, most of which were differentiated into two phenotypic classes, and a wide range of plant damage variation was characteristic of 16 accessions. The specific occurrence of resistant forms was the highest among oat landraces from Azerbaijan: two out of five studied accessions (40%) carry resistance genes with a distinct phenotypic manifestation. They are followed by accessions from Georgia (25%), Armenia (17.3%) and Dagestan (13.8%). After selection for resistance, the identified forms can be used in plant breeding.

The paper is dedicated to the investigation of adhesion strength in film coatings. The goal of the work is a qualitative estimate of the strength of film antifriction coatings applied on friction units of machines. The topicality is grounded by the fact that the friction decrease on surfaces in units ensures the increase of life, power effectiveness and reliability of machinery.
Most of the works are dedicated to the study of manufacturing films, their phase composition, structure, stress-strain properties, whereas in the material offered the adhesion properties of film antifriction coating are emphasized, which is a sufficient novelty.
During the investigations of the adhesion strength of antifriction film coatings there was used a method of a normal detachment. To carry out comparative tests there were prepared four groups of different antifriction coatings. For each coating under testing there were prepared five samples which were loaded with the smooth increase of a breaking tension.
Therefore there are obtained experimental dependences of normal stresses (σ) upon relative elongation (ε), which allow using values obtained for surfaces coated with antifriction film coatings with different areas. Upon completion of coating tests both parts of the samples tested were subjected to visual analysis. In the course of the analysis a character of destruction was defined. As a result of the theoretical and experimental investigations carried out there were drawn conclusions describing a qualitative and quantitative estimate of the adhesion strength of antifriction film coating.
DESIGN AND COMPUTATION OF THERMOMECHANICAL NUTRUNNER FOR LARGE DIAMETER THREAD TIGHTENING
Authors: Шишкин Сергей , Shishkin Sergey 
Published: October 2019

An original design of a nutrunner for tightening threaded joints of a large diameter is offered. The operation principle of the device consists in drawing out a bolt or a stud and in a free tightening of a nut for a specified angle. As a result of thread drawing out and a nut turn a value of a gap between its support surface and a flange plane will be already calibrated. An adjustment of a residual clearance after an effort relief from a power drive ensures a required value of tightening force.
A simplicity, reliability and compactness of the design is achieved at the expense of the application of a power element as a pipe made of alloy TN1 in which a return shape memory in the axial direction is initiated. Its operation principle is based on the regeneration of a reactive effort as a result of a phase transformation during heating because of the resistance of drawing out a bolt or a stud. An increasing force depends upon element dimensions, alloy energy and counteraction rigidity. That is to say, in contrast to hydraulics its value drops in the process of pipe elongation. For the force computation one uses a dependence upon a deformation value of power element length under-restoration (thermomechanical diagram), reasoning from which there is obtained a formula for the definition of the angle of a nut turn to ensure a required tightening of a threaded joint.
At the expense of high specific power of a thermomechanical power drive the device has comparatively small dimensions and mass. It allows installing a nutrunner set on each nut or on every other one and tightening all bolts of the joint simultaneously. The solution of the problem to ensure a uniform tightening of threaded joints keeps their initial life and reduces assembling labor-output ratio as it allows rejecting a technology of tightening bolts and studs located cross-wise with small pitches that are widespread in mechanical engineering.

Spiral Of Silence Theory Versus Perkembangan Masyarakat Suatu Penjelasan dan Kritik Teori
Authors: Hendra Yan 
Published: October 2019

<p><em>Spiral of Silence Theory</em> (Teori Spiral Keheningan) yang dikemukakan oleh Elisabeth Noelle-Neumann mengisyaratkan adanya keengganan seseorang untuk mengemukakan pendapatnya yang mungkin tidak sama dengan pendapat dari kebanyakan orang. Dalam perjalanan waktu, teori ini secara terus menerus mengalami proses pengujian pada saat teori tersebut digunakan oleh kalangan akademisi maupun masyarakat umum untuk menerangkan, meramalkan, menjelaskan fenomena komunikasi yang terus berkembang dan bervariasi. Seiring dengan kemajuan teknologi komunikasi dan informasi serta munculnya berbagai macam bentuk media baru telah berdampak kepada semakin meningkatnya keberanian orang dalam mengemukakan pendapatnya yang berbeda dengan pendapat dari kebanyakan orang. Dalam kondisi ini, Teori Spiral Keheningan ini tidak mampu secara lengkap dan akurat menjelaskan fenomena komunikasi yang menjadi perhatiannya. Hal ini membuktikan bahwa teori tersebut memiliki keterbatasan dalam menjelaskan fenomena. Kelemahan ini menjadi pembuka jalan bagi para ahli untuk melahirkan pemikiran baru dalam melakukan modifikasi teori maupun melahirkan teori baru. Teori yang tidak dapat lagi menjelaskan fenomena secara lengkap akan merubah teori tersebut menjadi sebuah asumsi saja.</p>

Published: October 2019

Abstract: Turn taking is simplest systematic for the organization of turn taking for conversation (Sacks, Schegloff, and Jefferson (1974). In conversation, sometimes the participant violate the rules as they begin to talk, meanwhile the other speakers are still speaking, and none of words and sentences to say in turn. Therefore, the writer was interested to analyze the violation of conversation rules in turn taking in order to investigate kinds of violation of conversation rules in turn taking that happened in the second step class of CEC Mataram, especially in debating activity by using a descriptive qualitative design. Then, the data were collected through video-recording from the second step class members of CEC Mataram. They were about 65 students and one teacher. Based on finding of this study, the writer found out five violations, such as violation of pause, gaps, laps, overlaps, and interruption. The first highest violation was pause violation with 135 times (81.3%) implies that the speaker in debating activity was silence within the turn given. The second one was interruption with 15 times (9.1%) implies that the other speakers began to talk when a speaker was speaking. The third was overlaps with 7 times (4.2%) implies that the speaker spoke at same time. The fourth was gaps with 5 times (3.0%) implies that the speaker did not talk directly when other speaker were given a chance to turn when one speaker was replaced. The fifth was laps with 4 times (2.4%) implies than none options for next turn is used when speaker change, the participant did not indicate backchannel during the debating activity (0% of violation).
