Aging-related variation of cuticular hydrocarbons in wild type and variant Drosophila melanogaster

The cuticle of all insects is covered with hydrocarbons which have multiple functions. Cuticular hydrocarbons (CHCs) basically serve to protect insects against environmental harm and to reduce dehydration. In many species, some CHCs also act as pheromones. CHCs have been intensively studied in Drosophila species and more specially in D. melanogaster. In this species, flies produce about 40 CHCs forming a complex sex- and species-specific bouquet. The quantitative and qualitative pattern of the CHC bouquet was characterized during the first days of adult life but remains unexplored in aging flies. Here, we characterized CHCs during the whole—or a large period of—adult life in males and females of several wild type and transgenic lines. Both types of lines included standard and variant CHC profiles. Some of the genotypes tested here showed very dramatic and unexpected aging-related variation based on their early days profile. This study provides a concrete dataset to better understand the mechanisms underlying the establishment and maintenance of CHCs on the fly cuticle. It could be useful to determine physiological parameters, including age and response to climate variation, in insects collected in the wild.

The Lithium Wars: From Kokkola to the Congo for the 500 Mile Battery

This paper presents an analysis and interpretation of the current state of play in the global value network of minerals mining, refining and transformation processes in the contemporary battery industry, which will power potentially crucial future industries for manufacture of electric vehicles (EVs) and solar-storage energy systems. The dark influence of the carbon lock-in landscape is gradually being mitigated under the challenge of achieving the “500 mile” battery charge, which would make a transformational difference in the replacement of renewably fuelled vehicles and storage systems, currently still predominantly driven by fossil fuels. The challenge has led to a “war” between manufacturers, miners and refiners, who have realised that the challenge has come alive while most have been vacillating. At an “individualist” rather than an “institutionalist” level, Elon Musk, for all his faults, deserves credit for “moving the market” in these two important industry sectors. This paper anatomises key events and processes stimulating change in this global economic activity through an “abductive” reasoning model and a qualitative “pattern recognition” methodology that proves valuable in achieving rational, probabilistic forecasts. Established incremental innovation characterises first responses in the “war” but research agencies like ARPA are active in funding research that may produce radical battery innovation in future.

Ben de Artık Bir Hikâye Anlatıcısıyım: Hikâye Anlatımında Dijital Olanaklar Açısından YouTuber “Fly With Haifa” Üzerine Bir İnceleme

One of the most basic needs of human beings is to communicate and throughout the history, people have used storytelling frequently to fulfill this need. Storytelling, which is one of the ways of expressing emotions and thoughts, has become important in different fields of communication studies day by day. It is possible to say that storytelling stands out in communication studies such as public relations, advertising, cinema, television, branding, political communication and digital communication. Storytelling is regarded as an important communication tool today, as it is in verbal culture, because digital technologies exist in social life as important tools that characterize communication. The study aims to examine the reflection of the transforming storytelling on digital environments in terms of content and technique. In the study, YouTuber “Fly With Haifa”, who is selected by YouTube as the Creators for Change in 2017-2018, is analyzed. Her video titled “Almost Bit by a Shark” is analyzed in terms of storytelling. The reason Fly With Haifa is chosen in the analysis is because it has a postmodern feature and it unites East and West in the video. In the study where content analysis technique was used with a qualitative pattern, content and technical analyses were used to understand how digital stories created through “Fly With Haifa”. As a result of the analysis, it was found that the basic components of the story, the story itself, the narrator, and the listener - although the basic elements of the story remain the same - have been transformed in terms of technique and content.

On the Impact of Germs and Demons

Historical and experimental analyses suggest contradictory deviations from efficient reasoning. In some cases, people tend to oversimplify and ignore important factors like germs, while in others they seem to overcomplicate and consider non-existent factors like imaginary demons. The current study shows how this apparent contradiction can be the product of a tendency to rely on small samples of past experience. Simulations demonstrate that reliance on small samples triggers apparent over-simplicity when simple choice rules are counterproductive but better for most sets of samples; the opposite over-complexity bias emerges when the optimal rule is simple but fails in most samples. The descriptive value of this hypothesis is demonstrated in two preregistered studies with 300 Mechanical-Turk participants. Study 1 shows the qualitative pattern predicted by the reliance on the small-samples hypothesis. Study 2 compares alternative formulations of the sampling process and clarifies the importance of a distinction between choice and sampling processes.

This is in accordance with the definition of qualitative research, namely a research that produces descriptive data in the form of written or spoken words from people and from observable behavior. The research pattern that the researcher uses is a qualitative pattern, namely observing people (subjects) in their environment, interacting with them, trying to understand their language and their interpretation of the world around them. While the type of research used is descriptive research. Descriptive research is a type of research that provides an overview or description of a situation as clearly as possible without any treatment of the object researched. The results of the study explain that 1) Style (Uslub) used in the Al-Baqiyatushhalihat Islamic boarding school is a literal translation method 2) The advantage of translation is knowing grammar rules such as nahwu sharf and the drawback is that it is still difficult to find the essence of the discussion 3) The efforts of the ustadz increases the understanding of the book by scientific discussion (bahsul masail).The conclusion that the translation used is the translation of harfian and bahsul masail is an attempt by ustadz to increase understanding of the book

Concept of Rivalry in D.H. Lawrence’s Sons and Lovers

Sons and Lovers (1913) is one of D.H. Lawrence’s most prominent novels in terms of psychological complexities characteristic of most, if not all, of his other novels. Many studies have been conducted on the Oedipus complex theory and psychological relationship between men and women in Lawrence’s novels reflecting the early twentieth century norms of life. This paper reexamines Sons and Lovers from the perspective of rivalry based on Alfred Adler’s psychological studies. The discussion tackles the sibling rivalry between the members of the Morels and extends to reexamining the rivalry between other characters. This concept is discussed in terms of two levels of relationships. First, between Paul and William as brothers on the one hand, and Paul and father and mother, on the other. Second, the rivalry triangle of Louisa, Miriam and Mrs. Morel. The qualitative pattern of the paper focuses on the textual analysis of the novel to show that Sons and Lovers can be approached through the concept of rivalry and sibling Rivalry. Keywords: Attachment theory, Competition, Concept of Rivalry, Favoritism, Sibling rivalry.

A STUDY ON THE TIME METROPHOR AND THE ELIMINATED OF TIME: GULTEN IMAMOĞLU PAINTINGS

With this study, it is aimed to reveal that Gülten İmamoğlu’s paintings have established a what kind of relationship with the concept of “time”, and created what kind of universe as a result of this relationship. This study is significant because of that it is an analysis that reveals the relationship which underlying of how a painter handles “time” in her paintings. This research performed as a case study in a qualitative pattern. This study is an existing analysis study by using document analysis and the technique of interview. The case studies base on the questions of “how” and “why” and enable to examine the depth of an event or event that the researcher cannot control. This research look for an answer “What is going on?” with a explicitive approach. Collected data was resolved with content analysis. The investigation process was carried out by the researcher. Traditional man; with the belief of “eternal return”, he repeats archetypes and myths throughout the ages and realizes the interest of non-religious time. The relevance of non-religious time has eliminated the temporality of time and a sense of “time” where everything is finite. This is prevented from drifting to a “nihilist” end of man. Humanity which adopted social and spiritual integrity is protected by a “time” insight through the ages. This approach enabled man to see himself as a part of the cosmos and positioned him in a coherent existence with cosmic rhythms. In Mircea Eliade's book “The Myth of the Eternal Return”, the concepts of “repeat”, “archetype” and “myth” are discussed. The thinker went for a comparison by putting forward the characteristics of the traditional understanding of “time” and the historical approach of “historic”, and made conclusions. It can be said that the idea of “time” reflected in the paintings of Imamoglu is fed from the same source with the understanding of “time” determined by Eliade in the “The Myth of the Eternal Return”. This work is an attempt to interpret the artist's paintings on this plane. It is suggested that the paintings of Gülten İmamoğlu should be handled in the context of the “chaos”, “orgy”, “dark” and “water” archetypes as well as their relationship with time. Keywords: Gülten İmamoğlu, Mircea Eliade, The Myth of the Eternal Return, the eliminated of time, archetype, myth, culture, time

Coherence Shifts in Attribute Evaluations

In five experiments, people repeatedly judged individual options with respect to both overall value and attribute values. When required to choose between two snacks, each differing in two attributes (pleasure and nutrition), people's assessments of value shifted from pre- to post-choice in the direction that spread the alternatives further apart so as to favor the winner, thereby increasing confidence in the choice. This shift was observed not only for ratings of overall value, but also for each of the two individual attributes. The magnitude of the coherence shift increased with choice difficulty as measured by the difference in initial ratings of overall value for the two options, as well as with a measure of attribute disparity (the degree to which individual attributes "disagree" with one another as to which option is superior). In Experiments 2-5, tasks other than explicit choice generated the same qualitative pattern of value changes, confidence, and response time. These findings support the hypothesis that active consideration of options, whether or not explicitly related to value, automatically refines the mental value representations for the options, which in turn allows them to be more precisely distinguished when later included in a value-based choice set.

SEDIMENTATION OF A BIDISPERSE CLUSTER OF SOLID SPHERICAL PARTICLES

A new method for the experimental study of gravitational sedimentation of a polydisperse cluster of solid spherical particles in a viscous fluid is presented. The method is based on the preliminary ultrasonic mixing of the particles in a spherical container and assumes the introduction of a spherical cluster of particles at a given concentration and zero initial velocity into a fluid. This method is used to determine sedimentation characteristics of a bidisperse cluster of particles (steel balls, 2 and 3 mm in diameter) in silicone oil. A qualitative pattern of the cluster evolution, a sedimentation rate, and a drag coefficient are obtained. A comparative analysis of sedimentation characteristics of monodisperse and bidisperse particle clusters is carried out in the range of Reynolds numbers Re = (0.30÷0.66)·10−3. It is shown that, in contrast to a monodisperse cluster of particles, the drag coefficient of the bidisperse cluster of particles does not correspond to a correlation CD = 24/Rec for the Stokes sedimentation.
