During the austral spring of 2008, 48 km of multichannel seismic reflection data were collected on a sea-ice platform east of New Harbor, Southern McMurdo Sound, Antarctica. These seismic data were collected to support the Antarctic Geological Drilling Program whose goal is to recover sedimentary rock cores from the continental margin of Antarctica and to better understand the climatic, cryospheric, and tectonic history of Antarctica. A Generator-Injector air gun, deployed through holes drilled in the sea ice, was used for a seismic source, and reflected energy was recorded on a snow streamer

In Korea, the predominant natural disasters that occur include heavy rain, typhoons, heavy snow, and strong winds, with heavy snow ranking as the second most damaging natural disaster after heavy rain and typhoons. Damage caused by heavy snow includes not only direct damage from snow cover but also indirect damage due to traffic congestion; therefore, interest in heavy snow damage is increasing. Accordingly, in this study, a vulnerability index was established by conducting heavy snow vulnerability analysis employing the pressure-state-response (PSR) technique.

Understanding the mechanisms of snow adhesion to surfaces and its subsequent shedding provides means to search for active and passive methods to mitigate the issues caused by snow accumulation on surfaces. Here, a novel setup is presented to measure the adhesion strength of snow to various surfaces without altering its properties (i.e., liquid water content (LWC) and/or density) during the measurements and to study snow shedding mechanisms. In this setup, a sensor is utilized to ensure constant temperature and liquid water content of snow on test substrates, unlike inclined or centrifugal snow

This conversion facilitates the extraction of more discernible features for matching by transforming the problem from snow-covered to snow-free images. Subsequently, a multi-level feature extractio

Abstract. A new, two-layer canopy module with thermal inertia as part of the detailed snow model SNOWPACK (version 3.2.1) is presented and evaluated. As a by-product of these new developments, an exhaustive description of the canopy module of the SNOWPACK model is provided, thereby filling a gap in the existing literature. In its current form, the two-layer canopy module is suited for evergreen needleleaf forest, with or without snow cover. It is designed to reproduce the difference in thermal response between leafy and woody canopy elements, and their impact on the underlying snowpack or grou

The article deals with the aesthetic differentiation of the landscape in Z. Krasinski’s novel «Agai-Gan». The novel is a literary experiment in which the author presents the dilemmas of a person seeking freedom. «Agai-Gan» is perceived as a combination of historical novel and romance, enriched with an element of the Gothic genre, characterised by originality and colorful exotics, acoustic effects and a very sensual visualisation of the landscape. In his literary experiment, Krasiński probably tries to solve the dilemmas of an individualist entangled in the pursuit of freedom and power. Undoub

A new springtail genus and species of the family Onychiuridae, Troglaphorura gladiator gen. et sp. nov., is described from deep Snezhnaya (Snow) Cave System (-1760 m) in the West Caucasus. Postantennal organ with only a single unlobed vesicle, sense organ of third antennal segment with sensory rods of complex structure, foot complex with missing empodia and extremely long thin claws as well as relatively long appendages, primitive dorsal chaetotaxy and presence of 1+1 pseudocelli on the head posterior part are extraordinary characters within the family but diagnostic for new genus and species.

The systematic position of Zhuqinia, gen. nov. in relation to other paronellids is not clear because the new genus possesses pointed, heavily striated scales similar to species of Callyntrurini. However, unlike species in that tribe, it lacks dental scales. Instead, Zhuqinia, gen. nov. is more similar to the unscaled genus Paronellides (Cremastocephalini) in other characters (abundant tergal macrochaetae, 2, 2|1, 2, 2, ?, 3 ter

The new family Maamingidae is proposed for Maaminga, gen. nov., comprising two species, M. rangi, sp. nov. and M. marrisi, sp. nov., from New Zealand. The delicate and slender M. rangi, sp. nov. is common in forest, particularly kauri forests of the northern part of the North Island. The more robust and stocky M. marrisi, sp. nov., which is polymorphic for wing size (brachyterous and fully winged), appears to be associated with coastal scrub and forest, particularly on offshore islands, but is also found in alpine snow tussock. Maamingidae is nominally placed within the Proctotrupoidea, and is

The sagebrush cricket, Cyphoderris strepitans is one of only five extant species belonging to an ancient insect lineage, the Haglidae, believed to be ancestral to modern-day crickets and katydids (Orthoptera: Ensifera) (Morris and Gwynne 1978, Vickery 1989). C. strepitans occurs exclusively in mountainous areas of Wyoming and Colorado, where it is found primarily in high-altitude sagebrush meadow habitat. Adults become sexually active in May, shortly after snow melt, and remain active for the next 4-6 weeks. Pair formation is mediated through acoustic signaling by males, which functions to att

Two novel Chlamydomonas-like species, belonging to the Moewusii clade, have been described. The first species inhabits eutrophic and neutral to basic pH waters in Sweden and England. It is easily recognizable under a light microscope due to its morphology (a small green prolate spheroidal shape with a large and truncated papilla at its anterior end, two equal flagella, a single lateral eyespot, a basal nucleus, and a well-defined pyrenoid) and to its peculiar whole-body pendulum movement while resting on surfaces or attached to floating particles.

In classical Chinese literature, employing the literary motif of the ghost represents both the writers’ desire to escape the pattern of didactic literature promoted by Confucianism and their attempt to revolt against the rigidity of the Confucian dogma that is far too entrenched in reality and inhibits their creativity. Written during the Yuan Dynasty (1279– 1368) by Guan Hanqing (1225–1302), Snow in Midsummer presents the injustice of Dou’E who dies for a crime she did not commit, with the girl returning to the world of the living in the form of a ghost to obtain her justice.

Every experiment starts from the theoretical part where the senior students try to introduce the primary students to activities.
