Data Collection Procedure

The design of iron (Fe) and Copper (Cu) thermocouples has been carried out for temperature sensors. The sensor will be made of two different types of materials namely iron and copper. The reference temperature used is 10C. The data collection procedure is first of all a thermocouple with a hot junction is tied together with a solder as a heat source. Besides that, it is also tied to a factory thermocouple that functions as a calibrator. Then the other end of the thermocouple (cold junction) will be inserted into a container containing ice cubes. Then the ports for each thermocouple will be connected to a multimeter, each of which is used to measure temperature (0C) and voltage (mV). From the results of observations and analyzes, it was found that for iron and copper thermocouples had the following characteristics: Seebeck coefficient was 0.001, the mean temperature rises and falls respectively (106.17 ± 0.82) 0C and (118.67 ± 0.90) 0C. The sensitivity of the thermocouple is 0.5 mV / 0C with linearity of 0.9.

This article investigates the evolution of two different types of Web portals, one in Bangladesh and the other in Australia. The initial data collection was conducted in the early 2000s and revisited in 2009. The idea of a Web portal is not new, but in the last few years the portal concept has gained considerably in importance as new types of portal are developed and new uses found for portal technology. The article begins with a brief classification of the types of portals in use today and then considers some of the advantages conferred on a business in using portal technology. Developed and developing countries have different problems in making use of e-commerce and see the advantages and problems of using portals rather differently. In the article the authors examine and compare case studies of a Horizontal B-B Industry Portal in Melbourne, Australia, and a Vertical Industry Portal in Dhaka, Bangladesh.

AbstractA congruently melting phase of molar ratio 2:3 was identified in the system SbCl3/4-phenylpyridine. The structure consists of two different types of complex units: One SbCl3 molecule is bonded to one 4-phenylpyridine ligand only, whereas the other one forms a complex with two 4-phenylpyridine ligands. The SbCl3 unit in the 1:1 species is pyramidally shaped, whereas the SbCl3 unit in the 1:2 species displays a T-shaped geometry. The mean angle between the phenyl and pyridyl planes is 33.3°; mean bond lengths are 〈Sb-Cl〉 = 247.6 pm and 〈Sb-N〉 = 241.7 pm.

Objectives This study aimed to evaluate the use of two different types of music – cat-specific music and classical music – compared with no music, to reduce stress in cats during hospitalization. Methods Thirty-five hospitalized cats were randomly divided into three groups and each group received a different stimulus – cat-specific music, classical music or no music (control) – throughout their hospitalization. Respiratory rate, salivary cortisol and social interaction were documented. A blinded researcher performed the Cat Stress Score (CSS) during the video analysis of recordings at five specific times over 31 h of hospitalization. Results There was no difference in the mean CSS between cats listening to cat-specific music, classical music and control throughout the five evaluations. Cat-specific music had a higher percentage of positive social interactions than the other groups on the first evaluation ( P <0.05). The average respiratory rate was significantly lower in the classical music group vs control on the fourth evaluation ( P <0.05). Although statistically insignificant, the average respiratory rate decreased only in the classical music group during the five evaluations. Cortisol quantification did not seem to follow the CSS results. However, owing to the low and unrepresentative number of samples, it was not possible to perform statistical analysis on these results or a group sample comparison. Conclusions and relevance Both cat-specific music and classical music seem to have some benefit to hospitalized cats. The salivary cortisol analysis was not adequate nor useful to measure stress in hospitalized cats in our study.

SummaryFour thromboplastin reagents were tested by 18 laboratories in Europe, North-America, and Australasia, according to a detailed protocol. One thromboplastin was the International Reference Preparation for ox brain thromboplastin combined with adsorbed bovine plasma (coded OBT/79), and the second was a certified reference material for rabbit brain thromboplastin, plain (coded CRM 149R). The other two thromboplastin reagents were another rabbit plain brain thromboplastin (RP) with a lower ISI than CRM 149R and a rabbit brain thromboplastin combined with adsorbed bovine plasma (RC). Calibration of the latter two reagents was performed according to methods recommended by the World Health Organization (W. H. O.).The purpose of this study was to answer the following questions: 1) Is the calibration of the RC reagent more precise against the bovine/combined (OBT/79) than against the rabbit/plain reagent (CRM 149R)? 2) Is the precision of calibration influenced by the magnitude of the International Sensitivity Index (ISI)?The lowest inter-laboratory variation of ISI was observed in the calibration of the rabbit/plain reagent (RP) against the other rabbit/plain reagent (CRM 149R) (CV 1.6%). The highest interlaboratory variation was obtained in the calibration of rabbit/plain (RP) against bovine/combined (OBT/79) (CV 5.1%). In the calibration of the rabbit/combined (RC) reagent, there was no difference in precision between OBT/79 (CV 4.3%) and CRM 149R (CV 4.2%). Furthermore, there was no significant difference in the precision of the ISI of RC obtained with CRM 149R (ISI = 1.343) and the rabbit/plain (RP) reagent with ISI = 1.14. In conclusion, the calibration of RC could be performed with similar precision with either OBT/79 or CRM 149R, or RP.The mean ISI values calculated with OBT/79 and CRM 149R were practically identical, indicating that there is no bias in the ISI of these reference preparations and that these reference preparations have been stable since their original calibration studies in 1979 and 1987, respectively.International Normalized Ratio (INR) equivalents were calculated for a lyophilized control plasma derived from patients treated with oral anticoagulants. There were small but significant differences in the mean INR equivalents between the bovine and rabbit thromboplastins. There were no differences in the interlaboratory variation of the INR equivalents, when the four thromboplastins were compared.

SummaryIn collaborative experiments in 199 laboratories, nine commercial thromboplastins, four thromboplastins held by the National Institute for Biological Standards and Control (NIBS & C), London and the British Comparative Thromboplastin were tested on fresh normal and coumarin plasmas, and on three series of freeze-dried plasmas. One of these was made from coumarin plasmas and the other two were prepared from normal plasmas; in each series, one plasma was normal and the other two represented different degrees of coumarin defect.Each thromboplastin was calibrated against NIBS&C rabbit brain 70/178, from the slope of the line joining the origin to the point of intersection of the mean ratios of coumarin/normal prothrombin times when the ratios obtained with the two thromboplastins on the same fresh plasmas were plotted against each other. From previous evidence, the slopes were calculated which would have been obtained against the NIBS&C “research standard” thromboplastin 67/40, and termed the “calibration constant” of each thromboplastin. Values obtained from the freeze-dried coumarin plasmas gave generally similar results to those from fresh plasmas for all thromboplastins, whereas values from the artificial plasmas agreed with those from fresh plasmas only when similar thromboplastins were being compared.Taking into account the slopes of the calibration lines and the variation between laboratories, precision in obtaining a patient’s prothrombin time was similar for all thromboplastins.

Thrombotic Tendency

SummaryWe have investigated the relevance of some laboratory tests of platelet function in predicting conditions of thrombotic tendency. For this purpose, we studied platelet survival, platelet aggregation in response to different stimuli, TxB2 and 6-keto-PGFlα production in serum of rats bearing a nephrotic syndrome induced by adriamycin. These animals show a heavy predisposition to the development of both arterial and venous thrombosis. The mean survival time was normal in nephrotic rats in comparison to controls. As to aggregation tests, a lower aggregating response was found in ADR-treated rats using ADP or collagen as stimulating agents. With arachidonic acid (AA) we observed similar aggregating responses at lower A A concentrations, whereas at higher AA concentrations a significantly lower response was found in nephrotic rats, despite their higher TxB2 production. Also TxB2 and 6-keto-PGFlα levels in serum of nephrotic rats were significantly higher than in controls. No consistent differences were found in PGI2-activity generated by vessels of control or nephrotic rats.These data show that platelet function may appear normal or even impaired in rats with a markedly increased thrombotic tendency. On the other hand, the significance of high TxB2 levels in connection with mechanisms leading to thrombus formation remains a controversial issue.

This journal explains the results of cohesion and coherence analysis in the current new news discourse in Indonesia published by Republika, Thursday 16 May 2019. The research uses descriptive methods by describing and explaining the results of the analysis found in the study. This research is a type of qualitative research because the results tend to be released and descriptive. the technique used in this study is to take data, data collection is done in two ways, namely listening and taking notes. This study found the results of the use of cohesion and and the use of coherence. Cohesion is the integration between the parts that are characterized by the use of language elements. Cohesion is divided into two parts, lexical cohesion and grammatical cohesion. Grammatical cohesion includes conjunction, reference, release, substitution. Lexical cohesion includes antonyms, synonyms, repetitions, metonymy, and hypomini. Whereas, cohorence is the relationship between elements one with the other elements so that it has an integrated meaning.

This paper describes a Voronoi analysis method to analyze a soccer game. It is important for us to know the quantitative assessment of contribution done by a player or a team in the game as an individual or collective behavior. The mean numbers of vertices are reported to be 5–6, which is a little less than those of a perfect random system. Voronoi polygons areas can be used in evaluating the dominance of a team over the other. By introducing an excess Voronoi area, we can draw some fruitful results to appraise a player or a team rather quantitatively.
