Wychodnie rud miedzi na terenie ukrainy zachodniej jako baza surowcowa metalurgii kolorowej w okresie funkcjonowania kultury trypolskiej

The article presents a study of copper ore from western Ukraine aimed at explanation of possibilities of their exploitation for the color metallurgy development during the period of Tripolye culture. It gives a short characteristics of lithological, mineralogical, and geochemical composition of copper ores from the Dneper area, Volhynia, and the Carpathians plateau. It further presents results of chemical and spectral analysis of ore-bearing rocks, evaluation of its current state and potential possibilities of their use in the past. Based upon a statement that metal objects produced during the existence of the Tripolye culture were made of pure copper two methods of its procurement were considered: (a) from a virgin copper, and (b) from oxygenated copper ore of sedimentary origin in which a small number of admixtures was noticed. The paper shows the potential of studies aimed at explanation of the correlation between contemporary and past copper ores and some copper goods from archaeological sites of the Tarnopol region.The article presents a study of copper ore from western Ukraine aimed at explanation of possibilities of their exploitation for the color metallurgy development during the period of Tripolye culture.

О значении капнометрического исследования при обследовании курящих лиц и больных с начальными проявлениями хронической обструктивной болезни легких

The aim of this study was to evaluate diagnostic value of capnography for early detection of lung function disorders in smokers. Methods. We compared results of capnography and spirometry and selected the most informative capnographic parameters in three groups of patients (n = 25 each): in non-smokers with normal spirometry, in smokers with normal spirometry and both in smokers and non-smokers with airway obstruction. Curves were obtained for continuous measurement of CO2 partial tension (PCO2) against time and volume. Results. A significant increase in the slope of capnographic alveolar phase during both tidal and deep expiration and a tendency to alveolar hyperventilation were found in obstructive patients. Similar, but less prominent results were obtained in smokers with normal spirometry. Conclusion. Capnography could be useful for early detection of lung function disorders in smokers before preceding occurrence of spirometric abnormalities (airway obstruction). PCO2 measurement against time was the most valuable parameter.Изучалась возможность использования капнометрии для выявления ранних нарушений функции легких у курящих. Сопоставлялись данные капно- и спирометрии, выявлены наиболее информативные показатели при проведении капнографии. В статье рассматриваются данные капно- и спирометрии (кривая поток–объем) в 3 группах: 1-я (n = 25) – некурящие с нормальными показателями спирометрии; 2-я (n = 25) – курящие (индекс курения – 3–63 пачко-лет; медиана – 17 (5; 25)) с нормальными показателями спирометрии; 3-я (n = 25) – курящие и некурящие с обструктивными нарушениями (у большинства – легкой степени; объем форсированного выдоха за 1-ю секунду > 70 %). Проанализированы показатели кривых, полученных при непрерывном измерении концентрации (парциального давления) углекислого газа (РСО2) по времени и объему. В 3-й группе отмечено значимое увеличение наклона альвеолярной фазы на капнограмме как при спокойном, так и при глубоком выдохе, тенденция к альвеолярной гипервентиляции. Во 2-й группе даже при нормальных показателях, полученных при спирометрии, выявлены аналогичные изменения, но менее выраженные. Сделан вывод о возможности использования капнометрии для выявления ранних нарушений респираторной функции у курильщиков до начала выявления обструктивных нарушений при спирометрии. Показано, что более информативным оказался анализ зависимости РСО2 по времени

Happiness around the world: A combined etic-emic approach across 63 countries

What does it mean to be happy? The vast majority of cross-cultural studies on happiness have employed a Western-origin, or "WEIRD" measure of happiness that conceptualizes it as a self-centered (or "independent"), high-arousal emotion. However, research from Eastern cultures, particularly Japan, conceptualizes happiness as including an interpersonal aspect emphasizing harmony and connectedness to others. Following a combined emicetic approach (Cheung, van de Vijver & Leong, 2011), we assessed the cross-cultural applicability of a measure of independent happiness developed in the US (Subjective Happiness Scale; Lyubomirsky & Lepper, 1999) and a measure of interdependent happiness developed in Japan (Interdependent Happiness Scale; Hitokoto & Uchida, 2015), with data from 63 countries representing 7 sociocultural regions. Results indicate that the schema of independent happiness was more coherent in more WEIRD countries. In contrast, the coherence of interdependent happiness was unrelated to a country's "WEIRD-ness." Reliabilities of both happiness measures were lowest in African and Middle Eastern countries, suggesting these two conceptualizations of happiness may not be globally comprehensive. Overall, while the two measures had many similar correlates and properties, the self-focused concept of independent happiness is "WEIRD-er" than interdependent happiness, suggesting cross-cultural researchers should attend to both conceptualizations

The economic well-being of nations is associated with positive daily situational experiences

People in economically advantaged nations tend to evaluate their life as more positive overall and report greater well-being than people in less advantaged nations. But how does positivity manifest in the daily life experiences of individuals around the world? The present study asked 15,244 college students from 62 nations, in 42 languages, to describe a situation they experienced the previous day using the Riverside Situational Q-sort (RSQ). Using expert ratings, the overall positivity of each situation was calculated for both nations and individuals. The positivity of the average situation in each nation was strongly related to the economic development of the nation as measured by the Human Development Index (HDI). For individuals’ daily experiences, the economic status of their nation also predicted the positivity of their experience, even more than their family socioeconomic status. Further analyses revealed the specific characteristics of the average situations for higher HDI nations that make their experiences more positive. Higher HDI was associated with situational experiences involving humor, socializing with others, and the potential to express emotions and fantasies. Lower HDI was associated with an increase in the presence of threats, blame, and hostility, as well as situational experiences consisting of family, religion, and money. Despite the increase in a few negative situational characteristics in lower HDI countries, the overall average experience still ranged from neutral to slightly positive, rather than negative, suggesting that greater HDI may not necessarily increase positive experiences but rather decrease negative experiences. The results illustrate how national economic status influences the lives of individuals even within a single instance of daily life, with large and powerful consequences when accumulated across individuals within each nation

THE GROWTH RATE PHENOTYPIC PROPERTY OF MYCOBACTERIUM TUBERCULOSIS CLINICAL STRAINS: DEPENDENCE ON TUBERCULOSIS LOCALIZATION, TREATMENT, DRUG SUSCEPTIBILITY

The phenotypic properties of the M. tuberculosis strains obtained from patients with pulmonary or extra-pulmonary tuberculosis are  determined by a complex set of factors: the genetic characteristics  of the pathogen, its ability to adapt in vivo and in vitro, the influence of the host’s immune system and chemotherapy. The growth rate as  the phenotypic property is the most accessible for the study of the  host-pathogen relationships at the level of host/strain population  interactions. The aim of the study is to assess in vitro of the growth  rate of M. tuberculosis strains isolated from patients with pulmonary  and extra-pulmonary tuberculosis: untreated and treated (with  surgical and non-surgical treatment) and also sensitive and resistant isolates in comparison with the reference strain H37Rv. To estimate  the growth rate of 116 clinical isolates we have used the modified  method originally developed by von Groll and co-authors: to get the  bacteria growth curve the fluorescence intensity of growing strains  (with indicator resazurin) has been measured daily for 8 days in 96- well plate. The growth rate is determined as the slope of the growth  curve. The mean values of the growth rate have been calculated in  the following groups of patients: 1 — untreated patients with  pulmonary tuberculosis (PT), respiratory material; 2 — non-surgical  treated PT patients, respiratory material; 3 — surgical treated PT  patients (mainly with chronic and hyperchronic process), respiratory  material; 4 — patients like in 3rd group, surgical material; 5 — bone  and joint tuberculosis (BJT), surgical material. In addition, groups of  sensitive and resistant strains have been examined, but there are no  significant differences in growth rates. It has been obtained that  the growth rate of strains isolated from the PT patients is higher than in BJT patients: it can be explained less favorable  conditions for the pathogen vegetation in the BJT. In the case of a  closed tuberculous lesion where the pathogen transmission to  another host is impossible, then the selection of strains with the  property to survive in the tissues of the osteoarticular system is  impossible too, therefor it should be observed only an adaptation of  the pathogen strain population to the individual host. The growth  rate of isolates from untreated PT patients is higher than that of the  treated ones. Comparison of the growth parameters of only MDR  strains 1–5 groups to eliminate the influence of the  sensitivity/resistance has resulted in the same conclusions. We  suggest that the decrease in the growth rate of strains from the  treated PT patients is in not only result of the treatment, but also is  conditioned by adaptation of the pathogen to its external  environment, which is the internal environment of the  macroorganism. To confirm this assumption, the bacterial load of  1,083 diagnostic specimens grouped in a similar manner has been  estimated, taking into account only MDR/XDR strains. In the group  of treated patients the frequency of high bacterial load (CFU ≥ 100)  reached 52.5–63.8% that shows the conserved fitness of bacteria in  such patients. The mean values of the growth rate of the strain  H37Rv non-adapted to the macroorganism (due to numerous  passages on artificial media) are higher than in all groups of clinical  strains. Thus, heterogeneity of phenotypic properties of M.  tuberculosis clinical strains on the basis of growth rate has been  obtained. The growth rate of M. tuberculosis clinical strains is  depended on the tuberculosis localization (PT, BJT) and on the joint  effect of patient treatment and pathogen adaptation to the host
