Textual Continuity

While textual variation has long been understood as a defining element of the genetic process, and indeed of textuality itself, this essay considers textual continuity not as the absence of revision but as potential revision that does not occur. In the archival materials associated with Toni Morrison’s and Tim O’Brien’s novels, we find various instances of a text remaining meaningfully the “same” across different versions. This emphasis on continuity implies a further possible reorientation, toward a sense of works in development, with individual documents construed less as physical objects or containers and more as “temporal parts”.

Genetic Improvement of Post-Heading Root Morphology and Physiology Facilitating Yield Increase of japonica Inbred Rice

Since genetic improvement greatly promoted an increased yield japonica inbred rice in east China after the 1990s, better root characteristics were certainly expected. In 2018 and 2019, nine japonica inbred rice released in the 1990s, 2000s, and 2010s were investigated to evaluate the changes in root morpho-physiology and identify root traits that contributed to the positive yield trends during the genetic process. The 2010’s rice had 8.0 and 4.3% higher grain yield than the 1990’s and the 2000’s rice, respectively (p < 0.05). Genetic yield gain was mainly attributed to the increased spikelets per panicle. Compared with the 1990’s and the 2000’s rice, the 2010’s rice had higher shoot biomass at heading and maturity (p < 0.05), as well as root biomass (p < 0.05), especially for root biomass of 15–30 cm soil depth. Leaf area index (LAI), soil-plant analysis development (SPAD) values, and leaf photosynthetic rate at middle grain-filling period (MGP) and late grain-filling period (LGP) were all increased. The 2010’s rice had consistently higher root length and volume, root oxidation activity, and root bleeding rate at MGP and LGP than the 1990’s and the 2000’s rice (p < 0.05). Positive correlations were detected between root length and volume, root oxidation activity, and root bleeding rate at MGP, LGP, and SPAD values, leaf photosynthetic rate at MGP and LGP, and higher shoot biomass accumulation after heading and grain yield (p < 0.05 or p < 0.01). The present study implied that genetic improvement optimized post-heading root morphology and physiology, which maintained shoot stay-green and facilitated biomass accumulation and yield increase in japonica inbred rice during the genetic process since the 1990s.

Relationship between second toe length and androgen-linked behaviours among students of Delta State University, Abraka, Nigeria

Background: During the formation of the limbs, a simultaneous production of androgens occurs. It has also been noticed that when genetic process is inhibited, it can lead to complications affecting the limbs. It is therefore believed that testosterone influences the development of the limbs. Aim: This study therefore looked at the association between second toe length and androgen linked behaviours. Materials and Method: Three hundred (166 males and 134 females) subjects who were students of Basic Medical Sciences, Delta State University, Abraka aged 18 and above, were selected using the cross-sectional descriptive study design. Second toe length was observed, standardize questionnaire on handedness, competition and aggregation was administered to students. Data obtained were analyzed with Statistical Package for Social Sciences. Results: This study established a significant association between 2nd toe length and some androgen linked behaviours. Significant association between subjects with longer 2nd toe and competitiveness was observed (p<0.05) as well as aggressive behavior. Conclusion: From this study, it was deduced that androgens influence 2nd toe length and 2nd toe length also influences androgen linked behaviours such as competition and aggression.

The collapse of genetic incompatibilities in a hybridizing population

Genetic incompatibility has long been considered to be a hallmark of speciation due to its role in reproductive isolation. Previous analyses of the stability of epistatic incompatibility show that it is subject to collapse upon hybridization. In the present work, we derive explicitly the distribution of the lifespan of two-locus incompatibilities, and show that genetic drift, along with recombination, is critical in determining the time scale of collapse. The first class of incompatibilities, where derived alleles separated in parental populations act antagonistically in hybrids, survive longer in smaller populations when incompatible alleles are (co)dominant and tightly linked, but collapse more quickly when they are recessive. The second class of incompatibilities, where fitness is reduced by disrupting co-evolved elements in gene regulation systems, collapse on a time scale proportional to the exponential of effective recombination rate. Overall, our result suggests that the effects of genetic drift and recombination on incompatibility's lifespan depend strongly on the underlying mechanisms of incompatibilities. As the time scale of collapse is usually shorter than the time scale of establishing a new incompatibility, the observed level of genetic incompatibilities in a particular hybridizing population may be shaped more by the collapse than by their initial accumulation. Therefore, a joint theory of accumulation-erosion of incompatibilities is in need to fully understand the genetic process under speciation with hybridization.

Die Glaubenskonzeption von Bernhard Welte

Bernhard Welte, a Catholic priest and German philosopher of religion, has a coherent and systematic conception of the faith. This study is meant to unfold the main elements and main characteristics of the conception of Welte, principally the nature of the faith, the genetic process of the faith and the difference between „daseinskonstitutiv“ and „daseinskonsekutiv“ belief.

The Taming of Matter: Jalmari Finne and the Typewriter

This article examines the role of the typewriter in the genetic process of the novel Vuosisatain vaatimus (1918) by the Finnish novelist Jalmari Finne (1874–1939). Finne is a rare example of an early twentieth-century author who mastered touch typing and composed directly on a typewriter. He claimed that he used the typewriter because it enabled him to keep up with his thinking, a claim that challenges Friedrich Kittler’s (1990, 193) thesis that the most remarkable feature of the typewriter is not its speed but its “spatially and discrete signs”. A genetic examination of Finne’s typescripts suggests that he had developed generative typing into a kind of “blind revision” in that he did not read and correct previous drafts but rather inserted a blank paper in the machine and typed an altogether new version of the text without copying the previous version.

Akt is required for artery formation during embryonic vascular development

SUMMARYOne of the first events in the development of the cardiovascular system is morphogenesis of the main embryonic artery, the dorsal aorta (DA). The DA forms via a conserved genetic process mediated by the migration, specification, and organization of endothelial progenitor cells into a distinct arterial lineage and vessel type. Several angiogenic factors activate different signaling pathways to control DA formation, however the physiological relevance of distinct kinases in this complex process remains unclear. Here, we identify the role of Akt during early vascular development by generating mutant zebrafish lines that lack expression of akt isoforms. Live cell imaging coupled with single cell RNA sequencing of akt mutants reveal that Akt is required for proper development of the DA by sustaining arterial cell progenitor specification and segregation. Mechanistically, inhibition of active FOXO in akt mutants rescues impaired arterial development but not the expression of arterial markers, whereas Notch activation rescues arterial marker expression. Our work suggests that Akt activity is critical for early artery development, in part via FOXO and Notch-mediated regulation.

The Diary, the Typewriter and Representative Reality in the Genesis of Juha Mannerkorpi's Päivänsinet

This article investigates the transition from keeping a diary to writing a future published work with reference to the genetic process of Päivänsinet: muuan loppukesän merkintöjä (1979) by Finnish author and translator Juha Mannerkorpi. The diary novel is about a seriously ill narrator who watches the growth of a morning glory, meticulously counting, measuring and registering the daily unravelling flowers with the help of a typewriter. In combining genetic criticism with Philippe Lejeune’s ideas on the diary, antifiction and the diary effect, the article analyses the frequent metapoetic remarks upon the use of the typewriter and the relationship between fact and fiction in the context of the diary-writing process and its subsequent rewriting as a novel. Upon close inspection of the manuscripts it becomes clear that the typewriter was not a transparent medium that helped the weak-sighted author to write, but that the physical act of typing influenced the content of Mannerkorpi’s text in many respects. In addition to shedding light on many experimental features of Mannerkorpi’s works, this study on the genesis of Päivänsinet widens current understanding concerning the impact of writing tools on diary-keeping and literary writing.

Targeting the hidden chromitite using geochemical vectoring for Bophivum area, northwestern Myanmar

&lt;p&gt;Harzburgite are the rocks that make up the mantle and consist of olivine, orthopyroxene, and clinopyroxene (&lt;5 %). Clinopyroxene contain Ca, Al, and Ti, while orthopyroxene contain Al. On the other hand, olivine contains almost zero contents of Ca, Al and Ti. When the rising melt from the lower mantle passes through the mantle harzburgite, the clinopyroxene and orthopyroxene with lower melting points compared with olivine are fused into the melt, and the olivine is crystallized from the melt. In this genetic process, harzburgite gradually change into dunite consisting of only olivine, and Ca, Al and Ti of pyroxene in harzburgite will escape into the melt. And, as the melting point of clinopyroxene is lower than that of orhopyroxene, the Ca, Al, and Ti in clinopyroxene are escaped into the melt earlier than those in orthopyroxene. The melt with changed composition formed by melting the pyroxene are mixed with the newly rising melt with pyroxene, so that the chromian spinel in the melt becomes saturated and the chromitite are formed. By the above-mentioned mechanism, chromitite occurs with dunite and pyroxene-deficient harzburgite formed by the reaction result between melt and harzburgite. In other words, in the genetic process of high Cr chromitite, the presence of melt that fused the pyroxene within harzburgite is essential. And, in order to make high Cr chromitite, the melt must have been fused more pyroxene in harzburgite. As a result, the Ti, Ca, and Al content of harzburgite will be decreased. Therefore, considering the representative chemical composition of podiform chromitite(Robinson et al., 1997), we assumed that as we approached into harzburgite bearing high Cr chromitite(probably hidden ore body), the Ti, Ca and Al content within harzburgite will be likely to converge toward the specific contents(Ti&lt;180ppm, Ca&lt;0.9%, Al&lt;0.7%). In case of Bophivum chromitite in northwestern Myanmar, it corresponds well with the representative chemical composition of high Cr chromitite in terms of the above-mentioned data. Therefore, we monitored to see whether Ti, Ca, and Al contents systematically change by the distance from the center with chromitite outcrop or high Cr anomaly zone confirmed through soil and rock geochemical exploration toward the surrounding harzburgite outcrop or not and tried to select the target element for geochemical vectoring using portable XRF. Conclusively, Ca is considered to be a more meaningful geochemical vectoring indicator than Al in terms of portable XRF measurements in the survey area.&lt;/p&gt;

Mineralogy, Geochemistry and Genesis of Zeolites in Cenozoic Pyroclastic Flows from the Asuni Area (Central Sardinia, Italy)

Natural zeolite occurrences have been recognized in several Cenozoic pyroclastic deposits in central Sardinia. This study concerns the mineralogical and geochemical characterization of the zeolitized tuffites in the Asuni area (Oristano province) and aims to complement information regarding the zeolitization processes developed in the nearby Allai deposits. Optical and scanning electron microscopy, X-ray powder diffraction, qualitative vs. quantitative microanalyses and bulk-rock geochemistry were performed. Analytical results allow defining the mineral distribution, textural relationships and geochemical features of the zeolite-bearing rocks. The most abundant secondary minerals are Ca-Na mordenites. Contrarily to the most common worldwide clinoptilolite + mordenite paragenesis, mordenite is dominant and occurs in different morphologies, rarely coexisting with clinoptilolite in the studied volcanic tuffites. Glauconite and dioctahedral smectite complete the authigenic assemblages. The primary volcanic components mostly include plagioclase, quartz and glass shards, roughly retaining their original appearance. The tuffites range in composition from dacite to rhyolite. The collected dataset shows that zeolitization is most abundant in coarser-grained deposits and points to a genetic process that mainly involves an open hydrothermal environment governed by aqueous fluids with significant marine component, in post eruption conditions.
