RESEARCH IN ROTARY PARLOUR OPERATION

The article summaries the results of rotary type milking parlour operation on five different farms. It has been stated that the milking equipment efficiency depends on the constructive solution of the milking equipment and the work of the milkers. For the herringbone Systems-20 milking equipment the technological productivity of work is in the frame from 83 to 100 cows·h -1 , herringbone Systems-32 - 133 cows·h -1 , but Side- by-Side Systems P-36 - 144 cows·h -1 . In most cases the milking equipment operation costs are from 150 to 165 LVL per cow per year. These costs can be reduced if the size of the herd is optimized. The desirable milking equipment loading coefficient is 0.7 - 0.8.
Loyalty to Community Modeling Through Value Co-Creation Behavior Activities With Perceived Benefit Mediation: Organic Food Product

: The current trend of people's lifestyles is to start consuming foods that are safe and environmentally friendly. The development of information on the usefulness of organic products more broadly becomes necessary. This study aims to determine the impact of value co-creation activities on loyalty to community, mediated by perceived benefit value. The analysis tool used in this study is Structural Equation Model (SEM) analysis. The sampling method used is a convenience sampling approach with 385 respondents. The results show that consumer perceived benefits value have a strong effect on loyalty to the community. In addition, value co-creation activities in the community is shown to be measurable by customer participation behavior and customer citizenship behavior to obtain the desired perceived benefits. The role of the community with the support of the loyalty of its members can be an effective means of disseminating knowledge about organic food products more broadly to the public. Having these results, the recommended policy direction is to increase the perceived benefits of customer community participation and citizenship. Further studies are needed to refine and build a more comprehensive model that integrates other theoretically related constructs.
Behavior of Cold-Formed Steel Plain Angle Columns

The main objective of this paper is to provide an efficient and accurate finite element model to understand the behavior of cold-formed steel plain angle columns. The effects of initial local and overall geometric imperfections have been taken into consideration in the analysis. The material nonlinearities of flat and corner portions of the angle sections were incorporated in the model. Failure loads and buckling modes as well as load-shortening curves of plain angle columns were investigated in this study. Furthermore, the residual stresses of a column test specimen were measured and plotted. The effect of residual stresses on the buckling behavior was studied using the finite element model. The nonlinear finite element model was verified against experimental results. The finite element analysis was performed on plain angles compressed between fixed ends over different column lengths, and column curves were obtained. An extensive parametric study was carried out using the finite element model to study the effects of cross-section geometries on the strength and behavior of angle columns. The column strengths predicted from the finite element model were compared with the design strengths calculated using the American Specification and Australian/New Zealand Standard for cold-formed steel structures. In addition, the results obtained from the finite element model were also compared with the design strengths obtained from the design rules proposed by other researchers.
Clustering-Based Plane Segmentation Neural Network for Urban Scene Modeling

Urban scene modeling is a challenging but essential task for various applications, such as 3D map generation, city digitization, and AR/VR/metaverse applications. To model man-made structures, such as roads and buildings, which are the major components in general urban scenes, we present a clustering-based plane segmentation neural network using 3D point clouds, called hybrid K-means plane segmentation (HKPS). The proposed method segments unorganized 3D point clouds into planes by training the neural network to estimate the appropriate number of planes in the point cloud based on hybrid K-means clustering. We consider both the Euclidean distance and cosine distance to cluster nearby points in the same direction for better plane segmentation results. Our network does not require any labeled information for training. We evaluated the proposed method using the Virtual KITTI dataset and showed that our method outperforms conventional methods in plane segmentation. Our code is publicly available.
VISION SCREENING OF FOUR- AND FIVE-YEAR-OLD CHILDREN IN CLUJ COUNTY: RECOMMENDATIONS FOR NATIONWIDE IMPLEMENTATION

BACKGROUND: Vision screening by measurement of visual acuity at age four or fi ve was implemented in Cluj County in 2018 and 2019. Our aim was to identify barriers and facilitators to implementation and to formulate conditions for nationwide implementation of vision screening in Romania. METHODS: In cities, children were screened by resident kindergarten nurses. In rural areas, kindergartens are small and have no nurses. Children were screened by family doctors’ nurses instead, initially at the doctors’ offi ces and later also at kindergartens. Because rural coverage was low in the fi rst year, a travelling screening nurse was employed to screen children in remote rural areas. Implementation was assessed with on-site observations, interviews, questionnaires and analysis of screening results, including ophthalmological examinations. RESULTS: In cities, 74.8% of eligible children were screened, in rural areas, 47.1%. The travelling screening nurse screened 805 children in seven months and rural communes where screening had taken place increased from 24 to 72 out of 75 during the second year. Referral rate was 15.8% initially, decreasing to 7.9%, varying between 0% and 57.1% among screeners. Of referred children, 27.8% were reported back by ophthalmologists, 15.3% were examined but not reported back, 21.4% were not examined and of 35.4% it was unclear whether they were examined. Referral and treatment were hampered by travel distance and lack of awareness. Of children reported back by ophthalmologists, 34.1% were prescribed glasses, 7.2% both glasses and occlusion and 0.7% occlusion. Vision screening was considered acceptable by respondents. However, in rural communes screening was deemed less appropriate and feasible. Fidelity was high in both urban and rural areas. * Corresponding author: Huibert Jan Simonsz, e-mail: simonsz@compuserve.com, Erasmus University Medical Center, Department of Ophthalmology, Rotterdam, the Netherlands Article received: 01.11. 2021, accepted: 16.11. 2021, published: 15.12. 2021 Cite: Kik J, Nordmann M, Rajka D, Mara M, Cainap S, Teodosescu O, Vladescu A Mocan A, Horwood A, Fronius M, Vladutiu C, Simonsz HJ.

Studs: a squat-type defect in rails

In the mid-2000s, a new rail defect that was initially classified as a squat became increasingly common on London Underground's track. By 2006, there were about 600 of these and they had become the Underground’s single most common rail defect. This defect occurred almost exclusively on lines carrying relatively new rolling stock. The work reported here was undertaken initially to characterize this defect, advise as to whether it was indeed a squat, and propose a hypothesis that explained its mechanism of formation. This paper includes observations and track measurements made in the field and initial results of a metallurgical analysis. The hypothesis for formation of the defects is presented, and both similarities and differences are discussed between these defects and the classical ‘squat’. The defect on London Underground appears to be the same as that described by Marich and his colleagues in Australia and by Li and his colleagues in the Netherlands. It is evidently not a conventional rolling contact fatigue defect. In order to avoid confusion arising from simple misuse of an established term, it is proposed that these defects be given a different name, for which ‘stud’ is proposed. Evidence to date is that the ‘stud' is a significantly more benign defect than the ‘squat’.
Experimental Narrative Structure and the Advent of New Humanism in Cormac McCarthy's The Road

This paper attempts to study the experimental narrative structure to explore postmodern new humanism in Cormac McCarthy's The Road. The study focuses on three inextricable narrative elements: the characters, narrative descriptions, and the novel's spatial setting. It will demonstrate how McCarthy's uses postmodern narrative experimentation to accentuate the necessity of halting the danger lurking behind the sustainable safety of the natural environment. Therefore, the study first examines the nameless characters of the novels as an exemplification of people who are devoid of their identity and sense of belonging due to natural catastrophes. Second, it identifies the narrative descriptions of the devastated environment ensuing gigantic disasters that obliterate the vast majority of the human civilisation. Third, it looks into the conditions of the remaining survivors as the embodiment of the remains of the human civilisation, and these survivors will be explored as the literary paradigm of new humanism living in a post-apocalyptic society leading a new primitive life from scratch. In this sense, the study gaps lie in exploring such new humanism as an archetype of postmodern civilisation surviving the destructive events and their related ethical dilemmas. As such, the study applies a qualitative methodology by following a textual analysis of the novel's characters, narrative descriptions, and spatial setting. Here, narratology will be applied as the theoretical background for interpreting these elements with regard to the post-apocalypse and its new humanistic insights. Thus, the study's main results are the exploration of the novel's apocalyptic events as narrative paradigms of new humanism and McCarthy's use of postmodern experimental narrative structure.
Bacteriophages and their microbial hosts in terrestrial biotopes of Antarctica

Abstract Virus diversity in Antarctic biotopes remains understudied. Here, we describe bacteriophages isolated from terrestrial environments, provide data on their natural bacterial hosts and study phage-host systems. Six bacterial isolates (FCKU 539, FCKU 533, FCKU 534, FCKU 538, FCKU 542 and FCKU 540) were recovered and characterized. Isolated bacteria belonged to Pseudomonas genus (Pseudomonas sp., Pseudomonas fluorescens, Pseudomonas putida) with optimal cultivation temperatures of 16–28°C. These bacteria and previously described Bacillus subtilis FCKU 537 were used for analysing virus-host interactions. Six lytic phages were isolated and named P. fluorescens Antarctic virus 1 (PFAV1), P. fluorescens Antarctic virus 2 (PFAV2), P. fluorescens Antarctic virus 3 (PFAV3), P. putida Antarctic virus 4 (PPAV4), Pseudomonas sp. Antarctic virus 5 (PSAV5) and B. subtilis Antarctic virus 6 (BSAV6) in relation to their natural hosts. According to electron microscopy data, these phages belonged to Caudovirales order. Cross-inoculation demonstrated high specificity of all Antarctic phages, which infected only their initial hosts at moderate temperatures. PFAV2 and PFAV3 phages also infected laboratory Pseudomonas savastanoi and P. fluorescens isolates. This paper adds new data on the occurrence and diversity of viruses and their respective bacterial hosts in soil biotopes of Antarctica.
Mapping The Drought Area Through Landsat 8 OLI/TIRS With LST Model SWA-S Method in Banyuwangi Regency

Drought-affected areas are critical to disaster reduction. The objective of the research is to discover how the drought spread with Landsat 8 OLI images, in particular by identifying the Land Surface Temperature (LST). The LST method involves determining vegetation emissions, known as the Normalized Dryness Vegetation Index (NDVI). The results showed that the drought location based on differences in land surface temperatures was in coastal areas and residential areas such as Banyuwangi and Muncar with 321-329 degrees Kelvin. Then in areas with Hills, topography shows the potential for drought with an area temperature of 308-321 degrees Kelvin. Furthermore, the field survey of temperature distribution accuracy-test revealed 90%. Based on these results, it can be concluded that LST can be used to identify drought with Landsat 8 OLI image
Modelling and test results of the Archimedes wave swing

Abstract The objective of this paper is to describe the modelling and some of the offshore test results of the full-scale model of Archimedes wave swing (AWS) at Portugal in 2004. The AWS is a system that converts ocean wave energy into electric energy. A pilot plant of this system has been built. The paper starts with the derivation of a model for the floater motion. Next, the generator system is described and modelled. The generator system consists of a permanent-magnet linear synchronous generator with a current source inverter. Subsequently, test results are presented to validate the models for the floater motion and the generator. Finally, some conclusions are drawn.
The role of Arctic ice reduction in the formation of climatic trends

This work considers a series of numerical experiments to identify the direct role of the sea ice reduction process in forming climatic trends in the northern hemisphere. We used two more or less independent mechanisms of ice reduction. The first is traditionally associated with increasing the concentration of carbon dioxide in the atmosphere from the historic level of 360 ppm to the level corresponding to the maximum concentration in implementing the mildest scenario RCP 2.6 - 450 ppm. Due to this growth, the average air temperature in the Arctic increases, and, by this, the ice volume decreases. The second mechanism is associated with a decrease in the reflectivity of ice and snow. As a result, the amount of solar radiation absorbed by the ice increases while the ice volume decreases. We assume that comparing the results of these two experiments allows us to judge the direct role of ice reduction, regardless of the reasons that caused this reduction.

High-performance work systems (HPWS) and individual performance: The mediating role of commitment

ABSTRACT The success of current and future military operations not only depends significantly on the explicit, technical, and tactical knowledge of the military personnel who execute them but also on their attitudes and behavior, such as courage, commitment, and high levels of readiness. Thus, using a sample of 336 military personnel exclusively from the operational component of the Portuguese Navy (PON) force system, the first aim of this study was to analyze the relationship between the perception of HPWS and the three dimensions of organizational commitment (OC), i.e., affective (AC), normative (NC) and continuance commitment (CC). The second aim was to analyze the mediating role of the three dimensions of commitment in the relationship between HPWS and performance, i.e., task performance (TP), contextual performance (CP), and counterproductive performance (CPP). The results obtained through the analysis of structural equation models made it possible to support a positive and significant relationship between the HPWS and each of the dimensions of commitment. The results also indicated that the AC has a mediating effect on the relationship between HPWS and performance, fully in the case of CP and partially in TP. In CPP, we observed that there is an indirect effect of HPWS and this dimension of performance. The theoretical and practical implications of these results are discussed.
Building Teams That Learn: Study of Learning Effects in Engineering Student Teams

Reviews of research on team learning generally show that it has positive and substantial effects on achievement Slavin 1995 . Team learning is believed to enable students to practice higherorder cognitive processes among peers in small groups Biggs and Moore 1993 . Team learning also helps improve social skills by peer discussion and argumentation Jacques 1991 . Students can be exposed to alternative perspectives and in this way develop critical thinking skills Banta 1993; Downes et al. 1991; Terenzini et al. 1995 . On the contrary, less is known about what factors contribute to team success or failure Chambers and Abrami 1991 . This research assessed the team learning method through students’ perception of its effectiveness. Various aspects in the implementation of team learning were also explored in an attempt to locate factors that may affect the outcomes of team learning. The objective of this research was to solicit students’ feedback regarding learning in small teams on a real-life problem-based subject entitled “Professional Studies,” undertaken by four classes of students majoring in building surveying BS , building engineering and management BEM , construction economics and management CEM , and real estate RE . Questions were clustered into three main areas related to team process, individual factors, and outcome in team learning, using a five-point Likert scale ranging from “strongly disagree” to “strongly agree. ” In addition, the questionnaire contained two open-ended prompts that asked students to list three items they liked and disliked most about working in teams. By using these open-ended prompts, it is hoped that students had the opportunity to voice their true opinions of working in teams, so that future problem-based projects can be tailored more toward working and learning in teams. This is a skill that is vital in real-world settings.
Spatio-Temporal Fish Catch Assessments Using Fishing Vessel Trajectories and Coastal Fish Landing Data from around Jeju Island

While pressure on marine ecosystems leading to declines in global fish catches have been attributed to excessive fishing and to unregulated and unreported fishing, existing management practices have yet to fully address these declines. Estimation of spatial and temporal distribution of fisheries resources and the extent of fishing impacts on marine ecosystems using vessel trajectories has become central in recent studies. This study proposed the use of trajectories of 771 Korean coastal and offshore fishing vessels and one-year fish landing data to estimate variations in commercial fish species, vessel, and fishing gear activity distributions in the waters around Jeju island. A set of standards were applied to identify individual fishing tracks of major gears and uniformly distributed catch to fishing segments of trajectories to produce spatio-temporal distributions of catch, fishing activities, and vessel reliance on fishing grounds at a fine spatial scale. The method identified reference points that can inform management at local and regional scales. We discuss the opportunities of combining larger datasets collected over a longer period and applying predictive modeling techniques in making extensive assessments, including climate change impacts on fishing activities that can inform resource management and marine spatial planning.
The Application of Active and Passive Remote Sensing Data for Drought Detection

This study aims to find out how to detect drought by examining distribution using active and passive sensors. Active sensors use Sentinel 1-A and RGB composites as a drought detection approach combined with vegetative indices. The passive sensors use Landsat 8 OLI/TIR with the TVDI method and emphasize the surface temperature and vegetation index. The results showed that active sensors with RGB Composites could distinguish drought conditions even with conspicuous residential areas. Whereas passive sensors with TVDI clearly show the propagation of drought. The TVDI itself is performed by knowing the relationship between surface temperature and vegetation index where the results indicate a high association of 0.99 and 0.97. It suggests that the 1-A sentry still needs a unique algorithm to identify droughts compared to Landsat.
Development of Closed-loop Control for Cavity Flows

Flow control is one of the main thrust areas of the Collaborative Center of Control Science (CCCS) at the Ohio State University. The primary objective of the flow control team at CCCS is to develop tools and methodologies for closed-loop flow control. The team possesses synergistic capabilities in all of the required multidisciplinary areas of flow simulation, low dimensional modeling, controller design, and experimental integration and implementation of the components along with actuators and sensors. The initial application chosen for study is closed-loop control of shallow cavity flows in subsonic Mach numbers. Shallow cavity flows have well known characteristics, are amenable to low dimensional modeling, possess known and localized receptivity, and are amenable to external forcing. Therefore, they are quite suited for closed-loop control technology development. The team has made significant progress in the development of various components necessary for low dimensional model based control strategy, which will be presented and discussed in this paper. The current experimental set up utilizes a titanium diaphragm compression driver for actuator, which is capable of forcing the flow up to about 10 kHz in the Mach number range of 0.25 to 0.5. While the low dimensional model based controller design is progressing steadily, a simple logic-based controller has been implemented, which can suppress the peak pressure fluctuations in the cavity up to 23 dB. The effectiveness of the controller is reduced at higher Mach number flows, presumably due to the lack of actuation authority.
