Abstract:

The term "Copper Hoard" refers to a number of copper implements were discovered occasionally, at a place, generally in the form of hoards, while ploughing a field or making a road. Copper hordes of Chota Nagpur, as well as Jharkhand, are unique and characteristically distinct from the other finds. The Earliest evidence of a copper hoard consists of five rough and unfinished copper celts, four of the five now are stored in the Indian Museum, and was found at Kaharbari in Pachamba. Though the chronology and the authorship of the Copper Hoard of Jharkhand as well as India are still being debated.

Abstract:

Data is nonrival: a person’s location history, medical records, and driving data can be used by many firms simultaneously. Nonrivalry leads to increasing returns. As a result, there may be social gains to data being used broadly across firms, even in the presence of privacy considerations. Fearing creative destruction, firms may choose to hoard their data, leading to the inefficient use of nonrival data. Giving data property rights to consumers can generate allocations that are close to optimal. Consumers balance their concerns for privacy against the economic gains that come from selling data

Abstract:

The transition toward an intangible-intensive economy reshapes financial systems by creating a self-perpetuating savings glut in the production sector. As intangibles become increasingly important, firms hoard liquidity to finance investment in intangibles of limited pledgeability. Firms’ savings feed cheap leverage to financial intermediaries and allow intermediaries to bid up asset prices, which in turn encourages firms to save more for asset creation. This paper develops a macrofinance model that offers a coherent account of rising corporate savings, debt-fueled growth of intermediaries, de

Abstract:

This paper studies the limitations of monetary policy in stimulating credit and investment. We show that, under certain circumstances, unconventional monetary policies fail in that liquidity injections into the banking sector are hoarded and not lent out. We use the term “credit traps” to describe such situations and show how they can arise due to the interplay between financing frictions, liquidity, and collateral values. We show that small contractions in monetary policy can lead to a collapse in lending. Our analysis demonstrates how quantitative easing may be useful in increasing collatera

Abstract. Surface hoar size and location relate directly to avalanche initiation trigger points, and they do so in small-scale spatial distributions. Physically, surface hoar will grow where the snow surface is cold relative to the air and water vapour is plentiful. Vapour aside, snow cools at night primarily by longwave radiation emittance. Emittance can be restricted by clouds, trees, and terrain features. With 96 independent spatial point samples of surface hoar size, we show the extreme small-scale size variation that trees can create, ranging from 0 to 14 mm in an area of 402 m2. We relat

New categories for the climatic division of snowy areas according to their snow-cover character in mid-winter are proposed. They are a wet-snow region, a dry-snow region, an intermediate snow region and a depth-hoar region. The wet-snow region is defined as the region in which every layer of deposited snow is wet due to percolation of snowmelt water throughout the winter. In contrast, areas in which the snow cover is dry, at least in the coldest period of the winter season, are classified into two categories, that is the dry-snow region and the depth-hoar region. In the latter region, the smal

Heat and mass transport by an air and water-vapour mixture (pore air) in snow due to thermal convection has been computed. It can be shown theoretically that thermal convection is always occuring in newly fallen snow, but never occurs in snow with rounded grains. Rayleigh numbers of depth hoar and partly settled snow are close to the critical Rayleigh number, therefore a small change in one or more of the snow parameters will decide whether there is convective or conductive heat transport.The influence of thermal convection on the mass transport rates of water vapour in snow is computed based

AbstractLayering affects the air flow through snow caused by surface pressure variations. The horizontal and total fluxes are high in hoar layers but the pressure perturbations and vertical components of the flow do not penetrate as deeply as in homogeneous snow. That is because the layers “pipe” the flow horizontally toward the area of low pressure. An ice layer at the surface reduces the total flow everywhere. The flow decreases as ice-layer thickness increases and, in general, flow changes with permeability. However, the magnitude of the effect is proportionately weaker when the ice layers

Abstract:

Laryngocele is a sac-like, pathological enlargement of the Morgagni's ventricle, which occurs between the true and false vocal cords. This change is filled with air and is continuous with the lumen of the larynx. It is usually asymptomatic and is accidentally detected during radiological diagnostics. We present the case of a 54-year-old patient who came for examination due to a painless swelling in her neck on the left side, which lasted for 8 months and increased upon Valsalva's maneuver. Occasionally the patient was hoarse. By clinical otorhinolaryngological examination and computed tomograp

Water isotopes are key proxies to reconstruct past climatic conditions on our planet based on Antarctic ice core data. The accuracy of climate reconstructions depends on understanding the whole range of the processes involved in the formation of precipitation isotopic composition. The isotopic composition of precipitation in Central Antarctica has been studied in a number of works, but the difference between the isotopic composition of different types of precipitation has not yet been fully described.There are three main type of precipitation in Central Antarctica: snow, ice needles and hoar.

We studied the effect of habitat conditions on the activity of enzymes and contents of metabolites of the ascorbate-glutathione cycle in Plantago media leaves.

In the summer of 2006, dying hoary cress plants were found near Kugoyeyskoye in the Krylovskoy area of the Krasnodar Region of Russia. Plants had grayish white leaf spots on most of the leaves. In some cases, the diseased leaf spots dropped out of the leaves producing shot-holes. In most cases, the leaf spots coalesced and the leaves wilted and died. Diseased leaves were collected, air d
