Help Of Path Research Articles

Six Steps in Reading to Appraise Scientific Publications: Discover a Different Path.

Effectively reading scientific publications, for example, research/quality improvement, is an acquired skill. Critical appraisal identifies articles' strengths and weaknesses related to credibility and authenticity or appropriate standards. To stimulate rehabilitation nurses' interest/participation in reading to appraise published studies (using brief evaluation questions). Read in this order: (1) title, abstract, and key words (are these words clear and directly connected to identified problem?), (2) discussion and conclusion (how are results/findings interpreted; are there recommendations for actions?), (3) results/findings (do key outcomes relate to the problem?), (4) introduction and review of literature (what are main arguments for study/project; does the study build on what's already known?), (5) data collection and analysis methods (are materials/procedures described for gathering information and evaluation?), and (6) references (are citations accurate/up-to-date?). Steps taken on this path help close the gap in reading to appraise scientific publications, discovering ways to build evidence-based rehabilitation nursing practices.

High-speed mass transfer in the W–Cu pseudo-alloy

Tungsten–copper alloys are heat-resistance materials for aerospace industry. Structure stability during processing and exploitation is controlled by the diffusion processes. In particular, the microstructure evolution is determined by the diffusion of copper atoms in tungsten matrix. Several experimental studies report different diffusivity of copper, which can be associated with the discrepancy of activation energy of diffusion depending on the structure of grain boundaries in tungsten. We performed density functional theory calculations of vacancy formation energies, segregation energies, and migration barriers for copper atoms in certain high-angle grain boundaries of special type using nudged elastic band method. Based on this information we calculated the corresponding diffusion coefficients. We found that the diffusivities in the studied grain boundaries exceed the extrapolated experimental data obtained at low temperatures at least by five times. The obtained data on diffusion path help to explain the depth, from which copper is removed during the annealing of the W–Cu alloy at 1500 K.

Determinants and implications of travel motivations: international travellers visiting Cappadocia

PurposeThis paper aims to explore the determinants and implications of travel motivations of international tourists visiting the Cappadocia destination.Design/methodology/approachThe quantitative research method focusing on numerical data was used to test the proposed hypotheses, and the survey technique has been used to collect data. The research participants consisted of 363 international tourists visiting the Cappadocia region/Turkey and spending at least one night there. Confirmatory factor analysis was performed using the AMOS 22 package program to ensure the scales’ construct validity. Then, the structural equation model was established to test the study’s hypothesis, and these hypotheses were tested with the help of path analysis.FindingsAs determinants of travel motivations, while electronic word of mouth (eWOM) has a positive effect on travel motivation dimensions, the impact of travel risk perception is negative. Moreover, from the dimensions of travel motivations, novelty/learning and socialization positively affect destination loyalty. However, the influences of escape and relaxation and self-development are meaningless. Besides that, travel risk perception strongly impacts eWOM.Practical implicationsDestination managers and practitioners must maintain a higher level of tourist motivation and reduce tourists’ travel risk perception levels to improve destination competitiveness by constituting a more loyal customer profile. Moreover, eWOM platforms should be used efficiently.Originality/valueThis study points to a functional multidimensional model that contributes to the literature and guides destination managers and practitioners. The proposed framework of determinants and consequences of tourists’ travel motivation can also be applied in other service contexts.

Forgotten Index of Generalized Operations on Graphs

In theoretical chemistry, several distance-based, degree-based, and counting polynomial-related topological indices (TIs) are used to investigate the different chemical and structural properties of the molecular graphs. Furtula and Gutman redefined the F -index as the sum of cubes of degrees of the vertices of the molecular graphs to study the different properties of their structure-dependency. In this paper, we compute F -index of generalized sum graphs in terms of various TIs of their factor graphs, where generalized sum graphs are obtained by using four generalized subdivision-related operations and the strong product of graphs. We have analyzed our results through the numerical tables and the graphical presentations for the particular generalized sum graphs constructed with the help of path (alkane) graphs.

Retrieval of Slant Water Vapor Path and Slant Liquid Water from Microwave Radiometer Measurements during the DYNAMO Experiment

Observations during the Dynamics of the Madden–Julian Oscillation (DYNAMO) experiment focused on sensing atmospheric parameters, including vertical moisture profiles, cloud structure, precipitation processes, and planetary boundary layer properties, all of which are important for understanding and modeling the Madden–Julian Oscillation (MJO). These observations were performed using a variety of in-situ and remote sensors, including the S-band polarimetric and Ka-band (S-PolKa) radar, deployed by the National Center for Atmospheric Research (NCAR), and a colocated University of Miami microwave radiometer (UM-radiometer) operating at 23.8 and 30.0 GHz. These instruments sampled approximately the same volumes of the atmosphere at a variety of azimuth and elevation angles. The principal goal of this study is to develop a new retrieval strategy to estimate slant water vapor path (SWP) and slant liquid water (SLW) using UM-radiometer measurements from zenith to low elevation angles at a variety of azimuth angles. Retrievals of SWP along the radar signal path help to determine the error in radar reflectivity due to water vapor absorption. The retrieval algorithm has been developed using the vapor–liquid water ratio (VLWR) as well as both modeled and measured brightness temperatures for zenith to low elevation angles. Observation system simulation experiment (OSSE) results and measured radiosonde data have been used to determine that the retrieval uncertainty is less than 5% for integrated water vapor (IWV) and less than 12% for integrated liquid water (ILW). OSSE results for SWP show that the retrieval uncertainty is less than 8% at 5° elevation angle and less than 5% at 7° and 9°, while the mean difference between SWP retrieved from radiometer measurements and those retrieved from the S-PolKa radar during the DYNAMO campaign is less than 10% at 5° elevation angle and less than 7.5% at 7° and 9°. OSSE results for SLW show that the mean error is less than 24% for 5° elevation angle and less than 18% for 7° and 9°. Such retrievals of SWP and SLW help to characterize the distribution of water vapor and liquid water in the lower troposphere, which in turn may contribute to improvements in forecasting of convective initiation and precipitation.

Feature Analysis and Extraction of the Garment Layout Planning

Automatic cutting helps improve efficiency in modern garment production. The design of cutting Numerical Control System determines the speed and quality of cutting flow. The optimization of cutting path based on different marking project, which helps improve not only the efficiency but also the level of systematic intelligence. The optimization of automatic cutting path varies with different layout planning. The layout planning of style design is different, so the individual feature of automatic cutting movement is different. The difference reduces the efficiency of automatic cutting work. Therefore it becomes especially important to analyze and extract common and individual feature of the different garment marking. This paper makes in-depth analysis on the layout planning of enterprises dressing gowns. Through using the method of actual discharge case by comparing and mathematical statistics, from the frequency characteristics, the sample outline of linear features and the utilization rate of discharge, this paper abstracts the character of different schemes of the dressing gown, obtains the common and individual feature, generates the linear path configuration of different pattern. The linear path help automatic cutting system path optimization for scientific basis and technical methods.
