Abstract The way to determine whether the Indian scad (D. russelli) comes from the same stock or not, is using estimation morphology and biology. The kinship of D. russelli in the three waters is not too close, and it has a very distant kinship with D. macarellus and D. kurroides. D. russelli and D. macrosoma in Bali Strait and South Java is close. The results of the analysis show that two of five components of the characteristic morphometric factor of D. russelli in the three waters have a character differential percentage of 37.73% and similarity of 62.27%. The growth rate obtained (L∞) from Bali Strait is 26,16 cm FL, the growth rate coefficient (K) is 0,63 per year, and (t0) is -0,20 years length maturity (Lm) male 13,9 cm FL and female 16,1 FL. The type of foods that is found are 12 phylums. The growth rate obtained (L∞) from Southern Waters of East Java of 28,28 cm FL, the growth rate coefficient (K) is 0,83 per year, and (t0) is -0,18 year, length maturity (Lm) male 15,3 cm FL female 16,7 cm FL. Type of foods that is found are 6 phylums. The growth rate obtained in Madura strait has an asymptotic length (Loo) 24,63 cm FL ; K 0,63 per year and t0 -0,27 year. Indian scad is a carnivore with the main food is Zooplankton (61%). using the morphological and biological approach, it is found that the D. russelli caught in the three waters come from a different stock.

In micro-arc oxidation process, ceramic coating had a rapid growth all along by the way of constant current oxidation, and ceramic coating had a low roughness by the way of constant voltage oxidation. But few research focus on the mixed control process of constant current oxidation and constant voltage oxidation. In this paper we propose a variable parameter process that can combine the advantages of constant current and constant voltage oxidation for the first time. The growth kinetics of different technics was analyzed according to the change law of current and voltage. Surface topographs of ceramic coating were observed using scanning electron microscopy (SEM). The friction tests were carried out using a self-made friction tester. The results show that ceramic coating has an upper growth rate and a low roughness by the process of constant current+constant voltage oxidation. The ceramic coating has a high growth rate by process of constant voltage+constant current oxidation. The results of friction test indicate that the wear rate and roughness of ceramic coating are positive correlation at early stage of friction. While the ceramic coatings treated by different technics have the close wear rate at stable friction stage, which embodies the inner layer of ceramic coating has a well antiwear behavior.

The closed form expression for estimation of the crack initiation life at combined HCF/LCF loading is derived, and the way of reshaping the crack growth rate formulae in the form enabling their use in fatigue design at non-stationary loading is demonstrated. This new derived formula suggests an additional damage increase when crossing from one stress block to another. It is proposed to call this effect as “block crossing effect”. Herein, the reshaped crack growth rate formula is applied for the fatigue design of structures and components made of titanium alloy Ti-6Al-4V and subjected to combined HCF/LCF loading. For the stress history simplified in the way that it consists of one LCF stress block with number of cycles equal to number of start-up in-service operations, at load ratio r = 0, followed by one HCF stress block at load ratio r > 0 with summed-up all HCF cycles, the closed form expression is derived for estimating the crack propagation life at combined HCF/LCF loading. Smith and Haigh diagrams as design tool for estimating the fatigue strengths for designed fatigue life, known load ratio and various number of HCF cycles per one combined stress block, are obtained for same material and same loading.

The Way

Background:Knowledge on fundamental aspects of the influence of ‘stress’ on animal and human organisms is accumulating. In clinical situations, however, psychiatrists still do not use apropriate instruments to recognize and handle the impact of daily life stress. DSM-IV is insufficient in this respect.Objective:A different approach is sketched for clinicians to be able to integrate knowledge from research more effectively.Method:Application of a ‘broad’ biological view may reveal the significance of interpretation, emotion, impulse and reaction as stages of a ‘mental tract’, which is involved in processing the input of stressful situations.Result:This may lead to a more rational ‘targeting’ of pharmacological and psychotherapeutic strategies in clinical practice.Conclusion:A re-orientation of clinical psychiatry from mere classification towards a ‘broad’ biological approach may pave the way for a more rational and purposeful application of research findings to therapy.

Agitation Speed

In a metastable solution the particle growth rate of silicon dioxide increased with an increase in the initial supersaturation of the metastable solution and agitation speed in the ranges of 2.5 × 10−4 to 2.0 × 10−3 M and 300–1500 rpm, respectively. Based on a power law expression, the particle growth rate order was estimated as 2.0 independent of the initial supersaturation and agitation speed. Meanwhile, the particle growth rate coefficient was enhanced from 2.0 × 10−3 to 1.4 × 10−2 with increase in the agitation speed from 300 to 1500 rpm. From the experimental data, it would appear that the enhanced particle growth rate resulted from the promotion of molecular transport due to the agitation and driving force of the supersaturation in the particle growth process. A slight addition of sodium chloride into the metastable solution caused a marked reduction of the particle growth rate due to the inhibition of growth process by sodium chloride adsorbed on the particle. This effect of sodium chloride on the particle growth appeared in a significant drop of the particle growth rate coefficient from 4.5 × 10−3 to 8.0×10−4 with increase in the sodium chloride concentration from zero to 5.0×10−3 M, but not in the particle growth rate order. The influence of sodium chloride on the particle growth process of silicon dioxide predicted with a Langmuir isotherm matched with the experimental data.

Emotion plays a fundamental role in mental illness. A central part of understanding mental illness is to make sense of the fragile character of human emotional life. Emotion research has long been divided into a biological approach and cognitive approach, arguing that the nature of human emotions is to be found in either our specific human cognition or in our cross-species biology. In fact, although human emotions are indeed characterized by intentionality and cognitive structures, many human emotional phenomena, for example, our feelings and moods, are non-intentional and cognitively impenetrable. Phenomenological psychopathology can help to clarify this interplay without renouncing either the biology or the rationality of human emotions. It offers a phenomenology of human experience that allows us to make sense of how emotions feel combined with a hermeneutics of the existential significance of our emotions, that is, what they are and why we feel the way we do.

Abstract In this study is presented a mathematical approach that can be used to estimate the variability of the growth rate coefficient (λ), the total number of cases, and the midpoint of maximum infection due to the COVID-19 pandemic. The different parameters are quantified using one-year data set reported for Ecuador (from March 2020 to February 2021) and the (discrete or differential) logistic model. In particular, the results evidence that the most critical months of the pandemic in Ecuador were March and April 2020. In the following months, the outbreak continues with low growth rate values but in a variable way, which can be attributed to state health policies and the social behavior of the population. The estimated number of confirmed cases is around 409 K agrees with the data reported at the end of May 2021, validating the proposed mathematical approach.

This article explores the connections between identity and foodways of farmers and small-town inhabitants in Eastern Poland, showing that food may serve as a strong metaphor of identity and the way of building ties and upholding community. The main food idioms are linked with the idea of „our” food, food which is local, familiar and familial, and the notions based on the connection with a certain region (terroir), along with with its history, people, environment, taste qualities. These are embedded in the locality and connect ideas of food, health, relationality and moral values (work), which are key building blocks of local identity.
