The embedded composite spinning technology was applied in spinning the composite yarn of polyamide 66 and nomex .The relationship of the polyamide 66 and nomex’s content with the mechanical properties of composite yarn and hairiness was discussed. The method of cluster analysis was applied in analyzing the four kinds of yarn’s mechanical properties. And the results show that when the confidence interval is 95%, the significance of two kinds yarns were greater than 0.05. There is no significant difference between the programs. While the analysis of the hairiness data showed that the fourth solution’s harmful hairiness was much lower that the first solution’s. Therefore, the best solution is the fourth solution.

To investigate the relationship of MUC1, MUC5AC, and the syndrome of spleen and stomach, 109 subjects (34 peptic ulcer (PU), 62 chronic gastritis (CG), and 13 healthy volunteers (CON)) were included. All the subjects included were surveyed with questionnaire to classify them into damp-heat syndrome of spleen and stomach (DHSS), spleen-qi deficiency syndrome (SQD), and CON, examined by gastric endoscope, and biopsied. Rapid urease and methylene blue staining (MBS) were performed on every subject to diagnose for Helicobacter pylori (Hp) infection, and both were defined as Hp-positive. Hematoxylin and eosin (HE) staining was performed on every specimen to explore the histomorphology, inflammatory degree, and inflammatory activity of different groups; then Elivision™ plus kit was used to test the expression of MUC1 and MUC5AC. All the results of digital images were reviewed by two experts blindly. The inflammatory degree with Hp infection was higher than those uninfected or CON, but no significant difference was found between DHSS and SQD. And the expressions of MUC5AC with positive Hp was higher than those with negative Hp or CON regardless of the deficiency and solid syndrome of spleen-stomach but not for MUC1. We speculate that the deficiency and solid syndrome of spleen-stomach is a condition like Tai Ji symbol of dynamic equilibrium, showing the higher expression of MUC5AC but no change of MUC1 in the circumstance of Hp infection.

Abstract Deuber (2006) investigated variation in spoken Nigerian Pidgin data by educated speakers and found no evidence for a continuum of lects between Nigerian Pidgin and English. Many speakers, however, speak both languages, and both are in close contact with each other, which keeps the question of the nature of their relationship on the agenda. This paper investigates 67 conversations in Nigerian English by educated speakers as they occur in the International Corpus of English, Nigeria (ice-Nigeria, Wunder et al., 2010), using the variability in copula usage as a test bed. Implicational scaling, network analysis and hierarchical cluster analysis reveal that the use of variants is not randomly distributed over speakers. Particular clusters of speakers use particular constellations of variants. A qualitative investigation reveals this complex situation as a continuum of style, with code-switching as one of the stylistic devices, motivated by such social factors as formality, setting, participants and interpersonal relationships.

ABSTRACT Objective: To determine the relationship of the surgeon handedness and operative site laterality on operative duration and hearing improvement in otologic surgery, and to further explore whether this relationship may be related to surgeon experience. Methods:Design: Retrospective CohortSetting: Tertiary Private Teaching HospitalParticipants: Seventy-three (73) patients aged 18 to 65 years old who underwent primary ear surgery under general anesthesia between January 2016 and December 2019 were retrospectively divided into two groups: 39 contralateral and 34 ipsilateral. The operative durations and hearing improvements were compared using independent t-tests, with consideration of surgeon experience in years further stratifying patients. Results: There was no significant difference in operative duration, t(71) = 1.14, p = .26, between the contralateral (M = 281.95 minutes, SD = 71.82) and ipsilateral (M = 261.15, SD = 79.26) groups. This same pattern was more pronounced among surgeons with 10+ years of experience although there was also no significant difference in operative time, t(33) = 1.31, p = .19 for both ipsilateral and contralateral surgeries There was no statistically significant difference, t(36) = -0.72, p = .47, in overall mean hearing gain among patients in the contralateral (M = +2.22 dB, SD = 10.54) and ipsilateral (M = +5.12 dB, SD = 14.26) groups. Although the difference was also not statistically significant, t(16) = -1.94, p = .07 for contralateral (M = 0.00, SD = 5.43) and ipsilateral (M = +7.95 dB, SD = 11.52) procedures performed by surgeons with experience of 10 years or more, a mean hearing gain of +7 dB in the ipsilateral group compared to 0 dB in the contralateral group was notable. Conclusion: This study did not prove that regardless of surgeon experience, right-handed surgeons operating on the right ear and left-handed surgeons operating on the left ear have better ear surgery outcomes of operative duration and hearing improvement compared to right- handed surgeons operating on the left ear and left-handed surgeons operating on the right ear. Future studies on larger samples with more complete data may yet demonstrate this effect.

The study was designed to investigate the relationship of psychological well-being with depression and anxiety among heart patients.1 For this purpose, a sample of 200 patients was taken, including 100 men and 100 women, educated uneducated, employed and unemployed volunteers. The sample was taken from Nishtar Hospital, Combined military hospital and other private hospitals in Multan. The age range from 25 to 60 (mean age 43.085).2,3 Objective: To observe the effect of demographic variables (age, education, gender and source of finance) on psychological well-being and depression, anxiety in heart patients. Methods: 1. Low psychological well-being would be positively correlated with depression and anxiety. 2. Older age (above 50) heart patients would have low sense of psychological well-being as compared to younger age (above 35) heart patients. Results: Different statistical procedures were used to determine the relationship of psychological well-being with depression and anxiety among heart patients. Correlation was computed to see the relationship among variables. It was found that there is negative correlation between psychological well-being with depression and anxiety. Since the p-value in less than α (p-value < 0.01), so we reject null hypothesis Ho, and conclude that low psychological well-being is positively correlated with depression and anxiety. Conclusion: This study also finds out important findings on the role of stresses, feeling of worthlessness in depression and anxiety disorder. It is concluded that psychological well-being, depression and anxiety are not significant correlated with each other. Source of income or job and sex of the heart patients have significant effect on psychological well being. However there is no significant difference between men and women regarding the rate of depression and anxiety. Keywords: P-Value, Correlation, Null Hypothesis , Depression

Abstract A series of controlled high explosive shots were conducted by the Atomic Energy Commission in a salt mine near Winnfield, Louisiana, to investigate seismic decoupling theories. Two recording stations were used by the University of Michigan at various distances between 1.1 and 14.7 kilometers for a majority of these shots. Frequency analyses of the magnetic tape recordings were made and the results are presented showing the relationship of the frequency spectra as a function of charge size, distance from the source, and coupled vs decoupled shots. The smaller decoupled shots detonated in the large spherical cavities were observed to have somewhat higher predominate frequencies than the equivalent size coupled shots. A change in cavity size produced no significant difference in the shape of the spectra of the large decoupled shots.

Objectives: To study the relationship between serum free T3 (FT3), C-reactive protein (CRP), and all-cause mortality in patients with acute myocardial infarction (AMI). Design: Prospective multicentre longitudinal cohort study. Methods: Between December 2014 and December 2016, thyroid function and CRP were analysed in AMI (both ST- and non-ST-elevation) patients from the ThyrAMI-1 study. The relationship of FT3 and CRP at baseline with all-cause mortality up to June 2020 was assessed. Mediation analysis was performed to evaluate if CRP mediated the relationship between FT3 and mortality. Results: In 1919 AMI patients [29.2% women, mean (SD) age 64.2 (12.1) years and 48.7% STEMI] followed over a median (inter-quartile range) period of 51 (46 to 58) months, there were 277 (14.4%) deaths. Overall, lower serum FT3 and higher CRP levels were associated with higher risk of mortality. When divided into tertiles based on levels of FT3 and CRP, the group with the lowest FT3 and highest CRP levels had 2.5-fold increase in mortality risk [adjusted hazard ratio (95% confidence interval) of 2.48 (1.82 to 3.16)] compared to the group with the highest FT3 and lowest CRP values. CRP mediated 9.8% (95% confidence interval 6.1 to 15.0%) of the relationship between FT3 and mortality. Conclusions: In AMI patients, lower serum FT3 levels on admission are associated with a higher mortality risk, which is partly mediated by inflammation. Adequately designed trials to explore potential benefits of T3 in AMI patients are required.

The evolution of snow and glacier research in Switzerland is outlined. The settling, creep, viscosity and slipping of the snow cover are discussed in detail and the relationship of these comparatively simple processes to the more complex movements in a glacier are described. The importance of further research in glacier physics in connection with the crystallographic and mechanical properties of ice is stressed; certain preliminary laboratory experiments and some subjects for further research in the field are suggested. The Great Aletsch Glacier is recommended for this owing to the proximity of the Jungfraujoch Research Institute and facilities for transport by the Jungfraujoch Railway.

The importance of lameness in dairy cattle in UK in terms of its economic consequences and welfare considerations is well documented (Russel and others, 1982). While such epidemiological work has identified factors of importance in the aetiology of the various conditions associated with lameness it has been less successful in apportioning their relative importance, particularly for those conditions affecting the hoof. A series of experiments has been conducted at the West of Scotland College over the period 1983 to 1989 mainly investigating the relationship of nutrition and lameness. In one of these Manson and Leaver (1988) found a significant difference in the prevalence of lameness between two groups of cattle fed complete diets containing either 16.1 or 19.8% crude protein. They also found a significant increase in mean locomotion score (LS) and commented that further studies were needed to understand the dietary processes by which the hoof of the cow was predisposed to such problems.The objective of this experiment was to investigate the influence of the type of protein source in the concentrate upon the locomotion of the cows, the incidence and prevalence of lameness and finally on hoof hardness, shape, growth and wear.

Particulate catechol-O-methyltransferase (COMT) from rat liver has been solubilized by acetone treatment and partially purified. Results from the present study demonstrate that the solubilized, partially purified enzyme is similar to the cytosol COMT with respect to molecular weight, pH profile, sensitivity toward inhibitors, Mg2+ requirement, and substrate affinities. However, a comparison of the crude particulate COMT and the solubilized enzyme shows that there is a significant difference in their affinity for catechol substrates. This finding suggests that membrane protein and (or) lipid components may play an important role in catecholamine metabolism. The relationship of particulate COMT to [3H]norepinephrine binding was investigated. No correlation between the COMT and [3H]norepinephrine binding activities was observed in vitro.

Background Familial Mediterranean Fever and celiac disease are both related to auto-inflammation and/or auto-immunity and they share some common clinical features such as abdominal pain, diarrhea, bloating and flatulence. Objectives We aimed to determine the association of these two diseases, if present. Methods Totally 112 patients diagnosed with Familial Mediterranean Fever and 32 cases as healthy control were included in the study. All participants were examined for the evidence of celiac disease, with serum tissue transglutaminase IgA levels (tTG IgA). Results Totally 144 cases, 112 with Familial Mediterranean Fever and 32 healthy control cases were included in the study. tTG IgA positivity was determined in three cases with Familial Mediterranean Fever and in one case in control group. In that aspect there was no significant difference regarding the tTG IgA positivity between groups (P=0.81). Duodenum biopsy was performed to the tTG IgA positive cases and revealed Marsh Type 3b in two Familial Mediterranean Fever cases and Marsh Type 3c in the other one while the biopsy results were of the only tTG IgA positive case in control group was Marsh Type 3b. In HLA evaluation of the celiac cases; HLA DQ2 was present in two celiac cases of the Familial Mediterranean Fever group and in the only celiac case of the control group while HLA DQ8 was present in one celiac case of the Familial Mediterranean Fever group. Conclusions We did not determine an association of Familial Mediterranean Fever with celiac disease. Larger studies with subgroup analysis are warranted to determine the relationship of these two diseases.
