A section, almost 20 km long and up to 80 m high, through alternating layers of diamict and sorted sediments is superbly exposed on the north coast of the Kanin Peninsula, northwestern Russia. The ...diamicts represent multiple glacial advances by the Barents Sea and the Kara Sea ice sheets during the Weichselian. The diamicts and stratigraphically older lacustrine, fluvial and shallow marine sediments have been thrust as nappes by the Barents Sea and Kara Sea ice sheets. Based on stratigraphic position, OSL dating, sea level information and pollen, it is evident that the sorted sediments were deposited in the Late Eemian‐Early Weichselian. Sedimentation started in lake basins and continued in shallow marine embayments when the lakes opened to the sea. The observed transition from lacustrine to shallow marine sedimentation could represent coastal retreat during stable or rising sea level.
This work reports the first results of isotopic geo-chronological study of detrital zircons from sandstones of the Late Precambrian Enganepe unit, which belongs to the Pre-UralidesTimanides exposed ...in the core of large Hercynian anticline in the Enganepe Uplift, western Polar Urals. The presence of a tuffaceous admixture in sandstones indicates the volcanic origin of some zircons. Data suggest that they were left in the sediments as syngenetic tephra during volcanic eruptions, which produced a basaltbasaltic andesite andesitedaciterhyolite volcanic complex (Bedamel Group) close in age to the Enganepe unit.
Scholars of Holocaust literary narratives have identified the ways in which the uses of language, memory, and narrative/ testimony have shifted in these texts from realistic modes of representation ...to more hybrid and metafictional considerations of this epochal event. Independently, critics working within science fiction (sf) have examined the ethical underpinnings of the genre’s construction and indicated potential reasons for the proliferation of sf in the twentieth century vis-à-vis trauma theory and the particular historical and technological climate of the era. In an effort to examine Holocaust history and memory – particularly, the force of the Holocaust and its impact on Jewish populations born and raised in the United States – Philip Roth increasingly turns to sf tropes and constructions as he explores the Holocaust more and more directly in three major works: The Ghost Writer (1979), Operation Shylock (1993), and, finally, his alternate history text The Plot Against America (2004). As the American-born protagonists in each of these texts confront the existential destruction of 20th century Jewishness and the widening gyre of history, Roth introduces and increasingly orients his texts around classic sf tropes to explore the breakdown of representational modalities and material cause which mark his generation’s conception of the effects of the Holocaust, as well as the perception of borders within his generation’s conception of Jewishness. Roth’s use of cognitive novelty and alternate history reflect the New Jersey-born author’s coming to terms with questions of “us vs. them” regarding American and European Jewry, particularly in light of arguments made by scholars such as Dominick LaCapra and Giorgio Agamben with respect to the limitations of traditional eyewitness testimony and narrative forms following the Holocaust. Roth and his (self-styled) protagonists grapple with the fundamental paradox of representing the unrepresentable – responding to an event that has broken down the logics of comprehension and expression – and how these pressures are to be represented or explored by American Jews whose understanding of their relationship to the Holocaust and their fellow Jew is one of diminished distances between the US and what happened “over there.”

The farmers and vendors in the Philippines classify coconuts through knocking manually either by bare hands or knife as 'mala-uhog', 'mala-kanin' and 'mala-tenga'. The said technique is well-known ...but yet carries no scientific proof. Thus, the proponents conducted this study to develop a knocking device that automatically classify coconuts by characterizing its maturity according to meat thickness and peak frequency using Fast Fourier Transform (FFT) algorithm. Sixty coconuts were sampled; each being initially categorized by a 'mangangatok' to the stage it belongs using the conventional method. Each were knocked using a knife at a constant distance and then opened right after for the measurement of its meat thickness using a Vernier Caliper. The recorded sounds were then analyzed using FFT Algorithm in OCTAVE. Statistical analysis show that each of the three stages has high correlation between 0.869 and 0.897 in terms of meat thickness versus peak frequency. Results showed that 'malauhog' coconuts have peak frequency range of about 200 to 400 Hz, 400 to 600 Hz for 'malakanin' and 600 to 800 Hz for 'malatenga'. From these results, a standalone Arduino-based sound acquisition knocking device was developed. The Sound acquisition system is designed to be portable. Its functionality was tested by sampling 119 random coconuts. Results showed that out of 119 there were 10 errors made by the device, exhibiting 91.6% accuracy. The device has capabilities of classifying maturity stages of coconuts which provides efficiency for vendors and compatibility for consumers with no knowledge in the currently known method.
