Liquid Manometer

An automatic liquid manometer which operates on the basis of a position-detecting system is described. A slanting laser beam is directed to the meniscus of liquid in a glass tube manometer without a float and is reflected by the meniscus. The reflected spotlight is focused on a position-sensitive detector (PSD) through a lens. The application of external pressure to the manometer causes the position of the meniscus to change, and the pressure can be gotten indirectly by this position. The relationship of the output of PSD to the displacement of meniscus was investigated, and the fuzzy control rules were determined to make the meniscus back to its original position fast and stable. The system has been tested with good results.

Abstract Jeremiah 52 is valued among scholars for the insight it provides into the composition history of the larger book and its relationship to 2 Kings. Beyond the text-critical clues it provides, however, little is said about the relationship of Jeremiah 52 to the rest of the book. The chapter has been added to Jeremiah from its original position in 2 Kings 24–5 (or a common source), but it has been edited in the process. What follows is an exploration of a possible motivation for the addition of Jeremiah 52 to the larger book. Using the characters of Jehoiachin and Zedekiah as representatives of those who did and did not listen to the exhortation of the prophet, the editor uses the material of Jeremiah 52 to indicate that any future for the nation of Israel was located in—and would come out of—Babylon.

The application of traditional distance relay for four-parallel transmission lines is adversely affected by the mutual coupling between the lines. The result will lead to not achieved measured impedance calculation. And it has an effect on the operation of ground protection. In this paper, A new ground distance algorithm is proposed for single-phase grounding fault of four-parallel transmission lines. Based on the case of single-phase grounding fault, The first the relationship between fault point voltage and the voltage at protection installed location is presented by twelve-sequence component method. In the basis, According to the relationship of phase corner between the fault voltage and the fault current to eliminate the effect of fault voltage. The simulation results show that the new scheme has high sensitivity and reliability under different single-phase grounding fault of four-parallel transmission lines.

Glass fiber–halloysite nanotube (GF/HNT) nanocomposites were fabricated with different numbers of fiber layers and were exposed to a high-temperature water environment to analyze the role of the HNTs regarding the relationship of interface between the fibers and the moisture absorption behavior. The sections of the GF/HNT nanocomposite plates were divided, and the change in the moisture absorption rate was measured. As a result, the ratio of the HNT to epoxy resin was not related to the water deterioration phenomenon according to the fiber-laminated thickness. However, in the curing process after the vacuum bag molding, the external pressure that was applied to each interface influences the flow characteristics and promotes the occurrence of HNT agglomeration, which interferes with interfacial crosslinking.

abstract When a relatively small perceptible earthquake occurred near a tripartite net of high sensitivity in central Japan, a substantial difference was found between its 25 foreshocks and 173 aftershocks in the relation of frequency of occurrence and magnitude. For that study the coefficient “b” in the magnitude versus frequency equation is 0.35 for the former and 0.76 for the latter. A similar investigation has been carried out on the great Chilean earthquake of 1960, also accompanied by many foreshocks and aftershocks. Using four sensitive and suitably located U.S.C.G.S. stations, Eureka, Tucson, South Pole, and Byrd, foreshocks and aftershocks were located in addition to those reported by U.S.C.G.S. or B.C.I.S. Forty-five foreshocks and 250 aftershocks were found in a period of 33 hours before and 33 hours after the main shock. The same characteristic found for the Japanese earthquake was also found for the Chilean earthquake; i.e. the foreshocks showed a different picture from the aftershocks for the frequency of occurrence, and an appreciably smaller value seems to be valid for “b” of the foreshocks.

The purpose of the study was to identify the interdependence of the process of hardiness and psychological capital of the individual. The hardiness of the individual is considered as the main resource for turning life events into new opportunities and experience, despite the external pressure. The concept of psychological capital has relatively recently come into use. It expresses the general resource state of a person and is formulated as a property that makes it possible to evaluate one's achievements in life, and one’s potential. The article analyzes the theories of the personality hardiness and psychological capital in foreign and domestic psychological science and the relationship of a number of similar concepts and phenomena in it; the main components, characteristic features and the main signs of their interdependence. The conclusion drawn is based on the data of theoretical analysis and experimental research of the properties of personality and psychological capital. The experimental study covered individuals aged 19 to 25 (N=35). In the course of the study, two methods were used: "Hardiness test" (S. Maddi) and the test "Psychological capital" (F. Luthans). It was found that the basis of the interdependence between the components of hardiness and psychological capital are the following distinctive features – the relationship between "commitment" and "self-efficacy", the relationship between "commitment" and "optimism", the relationship between" control "and "self-esteem", the relationship between "challenge" and "self-esteem".

Introduction: Aortic stenosis (AS) and aortic regurgitation (AR) patients develop both myocardial hypertrophia and fibrosis. B-type natriuretic peptide (BNP) and troponin are biomarkers whose value in aortic valvular heart disease (VHD) remains controversial. Cardiac magnetic resonance (CMR) imaging can detect replacement myocardial fibrosis (MF) by using late gadolinium enhancement (LGE), and diffuse MF by using extracellular volume (ECV) based measures (relative - ECV fraction - and absolute - indexed ECV) calculated from T1 mapping. Data evaluating the relationship of these biomarkers with both types of MF are scarce in AS, and are missing in AR patients. Hypothesis: There is an association between preoperative BNP and troponin and preoperative MF measures in severe aortic VHD patients. Methods: Patients with isolated severe AS or AR were prospectively recruited to be submitted to CMR before surgery, including LGE and ECV measures quantifications. They also collected blood samples for quantification of BNP and high sensitivity T troponin. The relationship between biomarkers and MF parameters was evaluated using linear regression and nonparametric conventional tests. Results: The study population included 99 patients, 67 with AS and 32 with AR. BNP median was 63 (39-103) pg/mL and troponin median was 17 (5-34) ng/L, no difference between AS and AR (p=0.31 and p=0.88, respectively). BNP and troponin were associated with presence of LGE. BNP median was 47 (32-87) pg/mL without LGE vs. 87 (47-190) pg/mL with LGE (p=0.002). Troponin median was 13 (5-25) ng/L without LGE vs. 30 (10-71) ng/L with LGE (p=0.001). Regarding ECV measures, patients with ECV fraction higher than 28.25% had higher BNP levels (p<0.001) and patients with indexed ECV higher than 24.21mL/m 2 had higher troponin levels (p=0.015) (Figure 1). Conclusions: BNP and troponin are associated with quantity of MF in patients with severe aortic VHD with indication of intervention.
