To reduce the sediment transport capacity, shear stress needs to be reduced as well. The article describes work that has been done to find a way to make these reductions possible. The theoretical study and the approach proposed allowed us to obtain a general equation that determines conditions and calculates the most important parameters which support the reduction of shear stress. This describes the mechanism that erodes soils by free surface water flow. In a similar vein, we have shown that adding a short non-prismatic channel to the entrance of a prismatic channel, which has the same geometric shape, is a very powerful way to reduce shear stress. With the idea of reducing shear stress, we have shown that the water-surface profile type plays a key role and must therefore be included in future reflections on reducing the importance of shear stress. Additionally, the notion of efficiency was introduced that allows to evaluate the expected gain after the reduction of shear stress and adding a short non-prismatic channel. The laws of similarity applied to free surface flows allowed us to obtain an equation with several equivalence scales and compare different geometric shapes in terms of their efficiency in the reduction of shear stress.

Electroflotation is used in the water treatment industry for the recovery of suspended particles. In this study the bubble formation and release of hydrogen bubbles generated electrolytically from a platinum cathode was investigated. Previously, it was found that both the growth rate and detachment diameter increased with increasing wire diameter. Conversely, current density had little effect on the released bubble size. It was also found that the detached bubbles rapidly increased in volume as they rose through the liquid as a result of decreasing hydrostatic pressure and high levels of dissolved hydrogen gas in the surrounding liquid. The experimental system was computationally modelled using a Lagrangian-Eulerian Discrete Particle approach. It was revealed that desorption of gaseous solutes from the electrolyte solution, other than hydrogen, may have a significant impact on the diameter variation of the formed bubbles. The simulation confirmed that liquid circulation, either forced or induced by the rising bubble plume, influences both the hydrogen supersaturation (concentration) in the neighbourhood of the electrode and the size of the resulting bubbles.

Colm Tóibín’s 2009 novel Brooklyn accompanies Eilis Lacey, a native of Enniscorthy, Ireland of the 1950s on a reluctant voyage across the Atlantic. Her passage reconstructs a common experience of immigration and exile to New York for the Irish working class seeking to escape the lack of prospects in small-town Ireland after the Second World War. Caught as she is between two homes-the traditional Irish culture she emerges from and the new capitalist society of America to which she emigrates-Eilis is placed in a polemical relationship to the public sphere, staked on multiple grounds of in-betweenness: she is a woman, Irish, and an exile. Belonging, for her, is posited on a complex understanding of the tensions between national and transnational identities. Eilis’s parochialism, at first, and cosmopolitanism, later on, are both decisive characteristics that become driving forces behind her social integration and marriage prospects. She is initially barred from promising job and marriage opportunities due to her naivety and lack of sophistication. As an Irish female immigrant, Eilis becomes in the course of the novel a cosmopolitan from the margins, one of the newly uprooted, and ultimately a split self.

Objectives Recovery processes in leisure time influence the effect of psychosocial work factors on health issues. However, this function of recovery has been neglected in research regarding the influence of work-related risk factors on low back pain (LBP) development. The aim of this prospective study was to examine the function of psychological detachment – a relevant recovery experience – concerning the influence of psychosocial work factors on LBP development. A moderating function of detachment for the interplay of work factors and LBP was assumed. Material and Methods Sixty pain-free administrative employees of German universities completed an online survey 3 times during a 6-month period. Generalized estimating equations were used to estimate risk-factors of LBP. Results Analyses revealed an increased chance of LBP development for smokers and a decreasing chance when work resources were high. Detachment had no direct influence on LBP development, although it moderated the influence of work stressors and work resources on LBP. On the one hand, high detachment values seem to protect against an increased chance of LBP development when employees were confronted with high work stressors, while on the other hand high detachment values enhance the protective effect of high work resources. Conclusions The results indicated a moderating role of detachment concerning the influence of psychosocial work factors on LBP development. Therefore, it is necessary to include recovery processes in future research regarding LBP development and consequently in LBP prevention concepts. Int J Occup Med Environ Health 2017;30(2):313–327

Bubble-particle interactions play an important role in flotation. This study examines the behaviour of bubble clusters in a turbulent flotation cell. Particularly, the bubble-particle interaction characteristics in flotation are investigated. The bubble size in a flotation column was measured using an Olympus i-SPEED 3 high-speed camera. Relationships between the circulating volume, bubble size and bubble terminal velocity were discussed. Probabilities of collision, attachment, detachment and acquisition between bubbles and particles in different circulating volumes were calculated based on the flotation kinetic theory. Using the extended Derjaguin–Landau–Verwey–Overbeek (EDLVO) theory, the relationship between the potential energy and distance in bubble-particle interaction was analysed. The results demonstrated that as the circulating volume increased, the bubble size and velocity decreased. When the circulating volume increased from 0.253 to 0.495 m3/h, the bubble diameter decreased from 511 to 462 μm, and the corresponding bubble velocity decreased from 43.1 to 37.5 mm/s. When the circulating volume remained constant as the particle size increased, probabilities of collision, attachment, detachment and acquisition increased. When the particle size remained constant as the circulating volume increased, these probabilities also increased. At a constant circulating volume as the particle size increased, the absolute value of the total potential energy between the particle and bubble increased. When the distance between the bubble and particle was 30 nm, the energy barrier appeared.

Philosophers have long thought that what differentiates humans from mere animals is that humans are essentially rational. The rational nature of human beings lies in their ability to detach themselves from ongoing involvement and to ask for as well as give reasons for activity. According to the philosophical tradition, human action and perception generally should be understood in light of this ability. This essay examines a contemporary version of this conviction, one promulgated by John McDowell. McDowell follows the tradition in suggesting that people are always able to step back and to ask as well as answer why questions about what they are doing, i.e., they always have reasons for their actions. This essay shows that people have no reasons for many of the things they do. They often, instead, simply respond to shifting situational fields of attraction and repulsion. These attractions and repulsions cannot be captured in propositional form-any attempt to describe, or even just name, them turns them into objects and robs them of their motivational force. The demands of the situation are not available as reasons, but exist only as embodied in actions. McDowell, consequently, errs in claiming that conceptual capacities are inextricably implicated in human activity. Nor is the detached, rational way of being any more essential to human life than is involved coping.

Saint Teresa of Ávila intrinsically connects discernment of the spirits with her principal theme of inner prayer. The main constituents of her doctrine of prayer (obedience, humility, charity, detachment) also represent key motifs in her view on discernment. From this perspective, Santa Teresa’s sparse assertions can be integrated into a coherent doctrine on discernment of the spirits, founded in her deep religious experience. Discernment emerges as the core of Christian life and the genuine way in which the Divine Friend gives light for choices that make human persons grow in virtues and in inner freedom.

PL

Święta Teresa z Avili łączy rozeznawanie duchów z jej głównym tematem wewnętrznej modlitwy. Główne elementy jej doktryny na temat modlitwy (posłuszeństwo, pokora, miłość, dystans) stanowią również kluczowe motywy w jej spojrzeniu na rozeznawanie duchów. Z tej perspektywy skąpe stwierdzenia Świętej Teresy mogą być włączone w spójną doktrynę rozeznawania duchów opartą na jej głębokim doświadczeniu religijnym. Rozeznawanie jawi się jako rdzeń życia chrześcijańskiego i ważny sposób, w jaki Boski Przyjaciel daje światło dla wyborów, które sprawiają, że ludzie wzrastają w cnotach i w wewnętrznej wolności.

To study the detachment stress on the ripeness of strawberry fruit, physiological characteristics of strawberry fruit on and off plant during ripeness and senescence processes were investigated. The results indicated that the ripeness of strawberry fruit upon detachment was accelerated, in terms of firmness, soluble solid content and especially color development. The color of fruit off plant changed rapidly from white to full red in 1–2 days. The respiratory rate in fruit off plant was strengthened, higher than that on plant. Abscisic acid level and ethylene production in fruit off plant were also higher than those on plant and auxin degradation was exacerbated by detachment. Expression levels of FaMYB1, FabHLH3 and FaTTG1 were generally reduced with phenotypes of redder color and more anthocyanin accumulation in fruit off plant. Results also suggested that the detachment initially stimulated ethylene and abscisic acid production and auxin degradation, which modulated ripening-related gene expression and at last enhanced fruit pigmentation.

Aim of the study: Notwithstanding its clinical and empirical relevance, there is no consensus on how to conceptualize dissociation. This may be partly due to the conflicting results yielded on the factor structure of the gold-standard selfreport measure of dissociation (the Dissociative Experiences Scale-Revised; DES-II, Carlson and Putnam, 1993). In an attempt to advance research on this topic, we sought to explore the factorial structure of an Italian version of the DES-II. Material and methods: A sample of 320 subjects (122 inmates and 198 community participants) was administered the Italian version of the DES-II. Results: The Italian version of the DES-II showed good psychometric properties and replicated a two-factor structure. Items content seemed to support the distinction into two qualitatively different forms of dissociative experiences, described as detachment and compartmentalization phenomena. In line with the expectations, participants in the inmate sample reported higher rates of dissociative experiences than community participants, on both dimensions. Conclusions: This study provides further support for the validity of the Italian version of the DES-II for use with community and inmate samples. Furthermore, we corroborated previous evidence on a two-factor structure of the DES-II, which is consistent with theoretical assumptions describing two distinct, albeit overlapping, dissociative dimensions (i.e., detachment and compartmentalization).

Cel badania: Niezależnie od wartości klinicznej i empirycznej pojęcia, jakim jest dysocjacja, nie ma zgody co do właściwego sposobu jego konceptualizacji. Częściowo może to być spowodowane sprzecznymi wynikami analizy struktury czynnikowej złotego standardu wśród narzędzi do samooceny zjawisk dysocjacyjnych, jakim jest Skala Przeżyć Dysocjacyjnych (Dissociative Experiences Scale-Revised; DES-II, Carlson i Putnam, 1993). Mając na celu pogłębienie badań na ten temat, autorzy podjęli się analizy struktury czynnikowej włoskiej wersji skali DES-II. Materiał i metody: Badanie obejmowało próbę 320 osób (122 więźniów i 198 osób należących do populacji ogólnej). Zastosowano w nim włoską wersję skali DES-II. Wyniki: Włoska wersja skali DES-II wykazała dobre właściwości psychometryczne i została w niej zreplikowana struktura dwuczynnikowa. Treść pozycji na skali wydawała się potwierdzać istnienie podziału na dwie jakościowo inne formy przeżyć dysocjacyjnych, ujmowane jako oddzielenie (ang. detachment) i szufladkowanie (ang. compartmentalization). Zgodnie z oczekiwaniami więźniowie częściej zgłaszali występowanie przeżyć dysocjacyjnych niż osoby należące do populacji ogólnej, na obu wymiarach. Wnioski: Niniejsze badanie dostarcza kolejnych dowodów na zasadność stosowania włoskiej wersji skali DES-II w badaniach na populacji ogólnej oraz więziennej. Potwierdzono również poprzednie dane świadczące o dwuczynnikowej strukturze skali DES-II, co jest zgodne z założeniami teoretycznymi opisującymi dwa odrębne, choć nakładające się na siebie wymiary dysocjacji (tj. oddzielenie i szufladkowanie).

Punktem wyjścia dla artykułu jest rozdarcie tradycji socjologicznej pomiędzy poszukiwaniem neutralnego spojrzenia na swój przedmiot a społecznym zaangażowaniem. Autorka pokazuje, że napięcie to od ponad wieku nadaje rytm rozwojowi myśli społecznej oraz instytucji badawczych i akademickich. Analizuje trzy wątki we wspólnej historii socjologii i kultury kapitalizmu: pacyfikację, przemoc i ryzyko. Podkreśla rolę neutralności dla pacyfikacji kultury Zachodu. Twierdzi, że w późnym kapitalizmie dominującą tendencją w myśleniu o naukach społecznych jest zaangażowanie, co sprawia, że socjologia częściej podsyca społeczne lęki, niż sprzyja – jak neutralne postawy badawcze – pacyfikacji.

EN

The starting point is the chiasm in the sociological tradition between the quest for a neutral perspective and the social engagement. The author demonstrates that this chiasm has dictated the rhythm of the developments in social thought and research and academic institutions for more than a century. She analyzes three motifs in the common history of sociology and capitalistic culture: pacification, violence and risk. She also stresses the importance of detachment for the pacification in the Western culture. She claims that in late capitalism involvement has become a dominant tendency in thinking about social sciences, for which reason sociology is more of a fuel-provider for social fears than the factor favoring pacification, which is reserved for detached research attitude.

A view is presented on different roles which the bilayer part of the membrane and the skeleton play in establishing normal and some abnormal RBC shapes. The system is first studied at the level of elastic properties of red blood cell membrane where the latter is considered to be a trilayered structure. Then the contributions to the membrane energy are introduced which cause the membrane to become laterally inhomogeneous, in particular, the skeleton-bilayer interaction, the interaction between the membrane embedded molecules and the membrane curvature, and the distributional free energy of membrane embedded molecules. It is invoked that the role of skeleton in stabilizing red blood cell membrane is in keeping membrane integral proteins laterally distributed as homogeneously as possible.

In the interwar period the 63rd Infantry Regiment was stationed in Toruń and constituted a part of the 4th Infantry Division deployed on the area subordinate to the Corps District Command number VIII with headquarters in Torun. The article concerns the most important events connected with the course of military service in the regiment at the beginning of the second half of 1930s. It has been based mainly on a thorough and detailed analysis of the orders of the day from a 3-year period. It presents important events from the soldiers’ life, from conscription onwards. It also describes the oath of enlistment ceremony, the recruits’ religious life, daily schedule, additional trainings for conscripted and professional soldiers, punishments and bans, awards and recognition for service, participation in holidays and in secular and religious ceremonies. The paper acquaints the reader with the barracks life in time of peace and with the course of service in the discussed period. It also shows that during the service the military authorities not only put emphasis on strictly military and physical preparation but also recognized the need of raising a citizen and a conscious defender of the country.
