Compression and strength behaviour of viscose/polypropylene nonwoven fabrics

Compression and strength properties of viscose/polypropylene nonwoven fabrics has been studied. Compressionbehavior of the nonwoven samples (sample compressibility, sample thickness loss & sample compressive resilience) havebeen analyzed considering the magnitude of applied pressure, fabric weight, fabric thickness, and the porosity of thesamples. Based on the calculated porosity of the samples, pore compression behavior (pore compressibility, porosity loss &pore compressive resilience) are determined. Equations for the determination of pore compressibility, porosity loss, and porecompressive resilience, are established. Tensile strength and elongation as well as bursting strength and ball traverseelongation are also determined. The results show that the sample compression behavior as well as pore compressionbehavior depend on the magnitude of applied pressure. At the high level of applied pressure, a sample with highercompressibility has the lower sample compressive resilience. Differences in pore compressibility and porosity loss betweeninvestigated samples have also been registered, except in pore compressive resilience. Sample with the higher fabric weight,higher thickness, and lower porosity shows the lower sample compressibility, pore compressibility, sample thickness loss,porosity loss, and tensile elongation, but the higher tensile strength, bursting strength, and ball traverse elongation

Quality of clothing fabrics in terms of their comfort properties

Quality of various clothing woven fabrics with respect to their comfort properties, such as electro-physical properties, air permeability, and compression properties has been studied. Fabrics are produced from cotton and cotton/polyester fibre blends in plain, twill, satin and basket weave. Results show that cotton fabrics have lower values of the volume resistivity, air permeability and compressive resilience but higher values of effective relative dielectric permeability and compressibility as compared to fabrics that have been produced from cotton/PES fibre blends. Regression analysis shows a strong linear correlative relationship between the air permeability and the porosity of the woven fabrics with very high coefficient of linear correlation (0.9807). It is also observed that comfort properties are determined by the structure of woven fabrics (raw material composition, type of weave) as well as by the fabrics surface condition. Findings of the studies have been used for estimating the quality of woven fabrics in terms of their comfort properties by the application of ranking method. It is concluded that the group of cotton fabrics exhibits better quality of comfort as compared to the group of cotton/PES blend fabrics.

Mental Health Assessment of Cancer Patients: Prevalence and Predictive Factors of Depression and Anxiety

Background: Patients with oncological diseases often have mental disorders in the form of comorbidity. The aim of this study was to research the association of cancer with the presence of symptoms of depression and anxiety in primary health care patients.Methods: This prospective observational study done in 2020 included adult users of health care at the Health Center Trstenik, Central Serbia, aged 19 and over, both sexes, with a diagnosis of oncological disease. A research instrument to assess depressive symptoms is used PHQ-9 (The Patient Health Questionnaire) questionnaire, derived from PRIME MD- and (The Primary Care Evaluation of Mental Disorders), and the Beck Anxiety Scale (BAI) to register the presence of certain anxiety symptoms.Results: The largest percentage of patients had symptoms of mild (27.2%) or moderate depression (22%), while 18% reported symptoms of major depression. The level of depression was higher in older subjects, in the presence of chronic diseases with greater limitations of activity and the presence of difficulties in performing daily activities, with a more pronounced effect of pain on activity, the presence of stress. All subjects were characterized as persons with severe anxiety (score 26-63). The level of anxiety was higher in older respondents, in the presence of long-term illness, with greater limitations of activities and difficulties in performing daily activities, with a more pronounced influence of pain on performing activities and the influence of the media.Conclusion: Caring for the mental health of cancer patients must occupy a significant part of each country's national health policy

The Beauty Ideal in Chinese Luxury Cosmetics: Adaptation Strategies of Western Companies

The aim of this paper is to determine if the standardization strategies, widely implemented by the luxury companies in international markets, can successuflly adopted in the Chinese Markets. In order to verify this statement, we analyse the luxury cosmetics industry in a market characterized by evident cultural differences. The cultural differences have been studied in term of beauty ideals and consumers’ behavior and expectations. We study four western luxury cosmetics companies. Although the first moves were mainly shaped on replication and standardization, the cultural differences force the four western companies to transform their orientation towards adaptation. This finding was partially unexpected and suggests that for specific type of luxury products the adaptation and flexibility are required despite the drift to replicate the standardized marketing strategies. These results are consistent with those of other studies suggesting the need for a balanced approach of standardization and adaptation in managing the international strategies

The value of the post mortem analysis of carboxyhemoglobin concentration in the blood: A 15-year study

Introduction/Objective The purpose of this retrospective study was to assess carboxyhemoglobin (HbCO) concentration in all autopsy cases of fire and non-fire victims - all those who have been suspected to be under the influence of carbon monoxide (CO) in the Belgrade area during a 15-year period (1990-2005). Methods Correlations between the concentration of HbCO, circumstances of death, vital signs, and prior health conditions, smoking and history of alcohol-abuse, have been particularly analyzed in 192 autopsy cases. Results The investigation included 52 (27%) females and 140 (73%) males, their average age being 50.78 years. CO poisoning has been established as the cause of death in 74 cases (38%). The manner of death in 170 cases (89%) was an accident, in eight (3%) suicide, in two (1%) murder, in 11 (6%) natural death, and in one case the manner of death hasn't been established. Such distribution of the manner of death differentiates this study from others of similar type, and it is conditioned by the specificity of life in this region. Conclusion The predictors of a high HbCO concentration are the sex, cause of death, manner of death, soot aspiration, lower-degree burns. According to the results, we profiled a typical victim of CO poisoning.Uvod/Cilj Cilj retrospektivne studije bio je određivanje koncentracije karboksihemoglobina (HbCO) u svim slučajevima žrtava iz požara i onih koji nisu u vezi sa njim, na području Beograda, u periodu 1990-2005, odnosno svih sluačajeva za koje se sumnjalo da su bili izloženi ugljen-monoksidu (SO). Metode U 192 slučaja obdukcije posebno su analizirane: korelacija između koncentracije HbCO, okolnosti umiranja, vitalnih reakcija, prethodnog zdravstvenog stanja, pušenja i zloupotrebe alkohola. Rezultati Ispitivanje je obuhvatilo 52 (27%) žene i 140 (73%) muškaraca prosečne starosti 50,78 godina. Trovanje SO je utvrđeno kao uzrok smrti u 74 slučaja (38%). U 170 slučajeva (89%) radilo se o zadesima, u 8 (3%) o samoubistvima, u 2 (1%) o ubistvima. U 11 slučajeva (6%) reč je bilo o prirodnoj smrti, dok u jednom slučaju uzrok smrti nije ustanovljen. Ovakva raspodela diferencira ovu studiju od sličnih i uslovljena je specifičnostima života u regionu. Zaključak Prediktori visoke koncentracije HbCO su pol, uzrok smrti, način smrti, aspiracija čađi, stepen izgorevanja. Na osnovu rezultata napravljen je profil žrtve trovanja SO

Jensen type inequalities for pseudo-integrals of set-valued functions

The set-valued function in general is an important mathematical notion that plays a crucial role in several practical areas. Also, the Jensen integral inequality is a significant mathematical tool that has applications in many areas, such as statistics, statistical physics, information theory, etc. Since the pseudo-analysis is, as well, a theory of the vast area of possible applications, this paper is focused on the generalization of Jensen integral inequality for the set-valued functions done in the pseudo-analysis' background. For this purpose two cases of the semirings and the corresponding pseudo-integrals of set-valued functions have been considered. ©2010 IEEE

Myocardial bridges: A prospective forensic autopsy study

Introduction When the coronary artery, located subepicardially, submerges into the myocardium and appears again subepicardially after a short intramural course, it represents an embedded coronary artery, while the part of the myocardium above is a myocardial bridge. Objective We investigated the frequency of the embedded left coronary artery (LAD) in the autopsy material considering the descending branch of the LAD to be the most important one in the nourishment of the myocardium and myocardial bridges to be the most frequent in its area, as well as clinically important. Methods A prospective autopsy study of 975 cases was performed, including both, natural (21.33%) and violent (78.67%) deaths. The sample consisted of 74.56% males and 25.44% females. In order to discover myocardyal bridges and their characteristics, the hearts were examined by both transverse cuts and longitudinal openings of the LAD. Results Myocardial bridge was found in 78 cases (8.00%), more commonly in males (9.35%) than females (4.03%). The average length of the myocardial bridge was 21.85±16.10mm and thickness 3.744±1.48 mm. The common localization of the myocardial bridge was the proximal half of the LAD (89.74%). The upper part of the artery, proximal to the bridge, was a common site of atherosclerotic changes. Myocardial bridge was found in 12.50% of natural deaths, but in 13.38% out of all cases of sudden cardiac deaths. Conclusion Therefore, the presence of the myocardial bridge by itself is not predominant, but it is certainly a contributing factor to a sudden cardiac death.Uvod 'Poniruća koronarna arterija' je pojam koji se odnosi na slučaj kada koronarna arterija - inače lokalizovana subepikardno - ponire u miokard i ponovo se pojavljuje subepikardno, posle kratkog puta kroz mišić, pri čemu se mišić iznad nje naziva 'miokardni most'. Cilj rada Istraživali smo učestalost poniruće descendentne grane leve koronarne arterije u autopsijskom materijalu imajući u vidu da je ona najvažnija u ishrani srčanog mišića, da najčešće ponire u srčani mišić i da je vrlo značajna i s kliničkog aspekta. Metode rada Urađena je prospektivna autopsijska studija 975 slučajeva prirodnih (21,33%) i nasilnih smrti (78,67%). Uzorak je obuhvatio 74,56% osoba muškog i 25,44% ženskog pola. Radi otkrivanja miokardnog mosta i analize njegovih osobenosti, nishodna grana leve koronarne arterije otvarana je uzdužnim i poprečnim obdukcionim rezovima. Rezultati Miokardni most je utvrđen u 78 slučajeva (8,00%), češće kod muškaraca (9,35%) nego kod žena (4,03%). Prosečna dužina miokardnog mosta bila je 21,85±16,10 mm, a debljina 3,744±1,48 mm. Najčešća lokalizacija miokardnog mosta bila je u predelu proksimalne polovine descendentne grane leve koronarne arterije (89,74%), a aterosklerotske promene su najčešće ustanovljene ushodno od miokardnog mosta. Miokardni most je postojao u 12,50% slučajeva prirodnih smrti, odnosno u 13,38% slučajeva tzv. naprasnih srčanih smrti. Zaključak Postojanje miokardnog mosta nije predominantni činilac za pojavu naprasne srčane smrti, ali je njegovo postojanje faktor rizika za njen nastanak
