Jocelyne Wildenstein and her Trump World Tower apartment. (Getty, Realtor)Jocelyn Wildenstein, a socialite known for her extensive plastic surgery, went from billionaire to bankrupt. Now, creditors have sold one of three condo units she combined into a single residence at Trump World Tower in Manhattan.The unit on the 51st floor of the Midtown East tower was sold for $2 million, according to the New York Post. It was stripped of its interior.Wildenstein had demolished several walls and combined the units into a five-bedroom, 5,160-square-foot home, according to the report.The combined property hit the market in 2015, asking $17.5 million.The other two units are on the market for a combined $5.6 million, but can be purchased separately.The last major sale at Trump World Tower came in late December when Moonbeam Capital CEO Steven Maksin paid $9 million for a unit at the property.In addition to the catlike features plastic surgery has given her eyes, Wildenstein is known for her reported $2.5 billion divorce settlement from ex-husband Alec Wildenstein in 1999, according to the report. In 2018, she filed for bankruptcy. Wildenstein was reportedly living in Miami and shopping a documentary series about her life.[NYP] — Dennis Lynch Share on FacebookShare on TwitterShare on LinkedinShare via Email Share via Shortlink Share via Shortlink Tags CondominiumsManhattantrump world tower
Twenty-one monthly collections of the Antarctic limpet Nacella (Patinigera) concinna (Strebel, 1908) were obtained by divers at Signy Island, South Orkney Islands. A mean monthly population density of 123.7 ± 21.2 · m−2, mean biomass of 13.7 ± 2.7 g dry tissue wt · m−2, and annual production of 2.9 g · m−2 were recorded in the depth range 2–12 m below mean low water. Shell growth was slow with a maximum growth rate, in the first 3–5 yr of life, of 3 4 mm per year. Maturity was attained at 7–8 yr (21 mm length), and maximum size (41 mm length) at about 21 yr. Unique spawning behaviour was observed in two Austral springs, and data relating spawning to the spring increase in sea temperature were obtained.
1.Populations of two coexisting Antarctic Collembola were studied in the field and under constant conditions in the laboratory to determine their life cycles and to compare their energy utilisation. 2.In the field Parisotoma octooculata completes three to four moults during summer, overwintering either in the egg stage or in the fourth or fifth instars. Maturity is reached in the second year, with synchronous oviposition and hatching. Cryptopygus antarcticus has many overlapping generations, maturity is achieved in the third year and oviposition and hatching take place throughout the year. 3.In the laboratory P. octooculata has a faster rate of growth than C. antarcticus under constant conditions of temperature and humidity. Analysis of gut contents showed that the two species overlapped in their food range; the faster growth of P. octooculata being achieved by a faster consumption rate, since the two species had similar assimilation and production efficiencies. 4.The slower growth rate of C. antarcticus may not result from limited food availability, but from a better life cycle strategy for unpredictable environmental conditions. P. octooculata, which shows features more characteristic of temperate Collembola, may be a more recent Antarctic colonist.
The ionospheric signature of a flux transfer event (FTE) seen in EISCAT radar data has been used as the basis for a modelling study using a new numerical model of the high-latitude ionosphere developed at the University of Sheffield, UK. The evolution of structure in the high-latitude ionosphere is investigated and examined with respect to the current views of polar patch formation and development. A localized velocity enhancement, of the type associated with FTEs, is added to the plasma as it passes through the cusp. This is found to produce a region of greatly enhanced ion temperature. The new model can provide greater detail during this event as it includes anisotropic temperature calculations for the O+ ions. This illustrates the uneven partitioning of the energy during an event of this type. O+ ion temperatures are found to become increasingly anisotropic, with the perpendicular temperature being substantially larger than the parallel component during the velocity enhancement. The enhanced temperatures lead to an increase in the recombination rate, which results in an alteration of the ion concentrations. A region of decreased O+ and increased molecular ion concentration develops in the cusp. The electron temperature is less enhanced than the ions. As the new model has an upper boundary of 10 000 km the topside can also be studied in great detail. Large upward fluxes are seen to transport plasma to higher altitudes, contributing to the alteration of the ion densities. Plasma is stored in the topside ionosphere and released several hours after the FTE has finished as the flux tube convects across the polar cap. This mechanism illustrates how concentration patches can be created on the dayside and be maintained into the nightside polar cap.
On August 18, 1999, Cassini flew by the Earth on its way to Saturn. The Cassini Earth swing-by was the fastest traversal of the Earth’s magnetosphere to date. The spacecraft was traveling at 9.1 R-E hr(-1) (16.1 km s(-1)) and made rapid traversals of several regions of the terrestrial magnetosphere. During the Cassini Earth swing-by the Electron Spectrometer (ELS) collected almost 9 hours of data in the Earth’s magnetosphere and almost 10 hours of solar wind data upstream of the Earth. During the pass, Cassini ELS sampled electrons in the solar wind, bow shock, magnetosheath, magnetopause, radiation belts, plasmasphere, plasma sheet, lobes, and crossings of the tail magnetopause. The purpose of this paper is (1) to give a summary of electron observations including the locations of magnetosphere boundary crossings and (2) to assess how the ELS is functioning as it takes measurements in the greatly differing plasma regimes encountered. Results are shown to be mainly consistent with previous observations with a few exceptions. In addition to anticipated results we present evidence of a low-energy field-aligned beam in the plasma sheet and evidence of asymmetry on the dayside and nightside plasmapause position. Preliminary calculations of density and temperature for the solar wind, magnetosheath, and plasma sheet are also presented.
The hygropreference of adult Cryptopygusantarcticus and Alaskozetesantarcticus was investigated over 2 h at 5, 10 and 20°C, along humidity gradients (9–98% RH) established by means of different salt solutions. Two chamber arrangements were employed, linear and grid, to determine any influence of thigmotactic behaviour on distribution within the RH gradient. The humidity preference of both species varied with temperature. At 5 and 10°C, C. antarcticus distributed homogeneously showing no clear RH preference. At 20°C, this species preferred the highest humidity (98% RH). A. antarcticus demonstrated a preference for the lowest humidity (9% RH) at 5°C, but at 10°C its distribution differed between the two arena types. At 20°C, A. antarcticus showed no clear humidity preference. Assays to control for experimental asymmetries along the gradient; thigmotactic behaviour; and aggregative behaviour exclude these factors as explanations for the observed results. The mean initial water content of samples did not differ significantly between temperature regimes (C. antarcticus: 68.6, 71.1 and 74.3%; A. antarcticus: 68.1, 70.1 and 68.6% at 5, 10 and 20°C respectively), but the level of water loss increased significantly with temperature. The influence of desiccation tolerance and the ecological significance of the observed humidity preferences are discussed.
1] Lower thermospheric and upper mesospheric rotational temperatures have been derived from ground-based measurements of the O-2(0-1) and OH(6-2) nightglow emissions over Resolute Bay, Canada ( 74.68degreesN, 94.90degreesW) and OH(4-2) nightglow emission over Kiruna, Sweden (67.90degreesN, 21.10degreesE). From measurements taken during two nights in November, 2001, we have observed a dominant and coherent 4-hr oscillation in both the O-2 and OH airglow emission rates and rotational temperatures. The phases for the two oscillation events remain almost constant at each location, indicating that these oscillations may not be caused by transient passage of instantaneous gravity waves. More importantly, there is little phase difference in universal time between the 4-hr oscillations in temperature at Resolute and Kiruna. The small phase difference gives a strong indication that the oscillation maybe related to a zonally symmetric tide, since any tidal waves in temperature with a nonzero zonal wavenumber are very weak at high latitudes. Waves in both events have large vertical wavelengths (76 and 175 km). The 4-hr wave shows almost no latitudinal variation from Resolute to Kiruna.
Baleen whales are an important group of predators on Antarctic krill in the Southern Ocean. During the CCAMLR 2000 Survey to estimate the biomass and distribution of Antarctic krill, International Whaling Commission observers carried out a visual line transect survey to estimate the number of baleen whales occurring in the survey area. This paper reviews techniques used to estimate krill consumption by baleen whales and in combination with estimates of whale abundance estimates of krill consumption are generated for the South Atlantic sector of the Southern Ocean. This survey estimates that the present populations of whales feeding in this region are likely to consume approximately 1.6 million tonnes, but possibly up to as much as 2.7 million tonnes of krill within the summer season. Although this only represents 4-6% of the estimated krill biomass in the region (and probably less than this percentage of the total annual krill production), the depleted numbers of baleen whales resulting from past or current whaling activities should be taken into account when setting quotas for the commercial exploitation of krill if there is to be a recovery to pre-exploitation biomass levels of baleen whales.
Different parts of Antarctica receive different amounts of snowfall each year. In this paper we map the variations of the mean annual snow accumulation across the ice sheet. We also quantify the uncertainty in our estimates more objectively than has been possible for earlier maps. The new map is produced using observations from satellites and ground-based measurements. After a logarithmic transformation, these are combined using the geostatistical method of continuous-part universal kriging to give an estimate of the snow accumulation within each cell of a rectangular grid covering Antarctica. We also derive spatial averages over the major drainage systems of the ice sheet, along with their confidence intervals. We obtain a value of 143 ± 4 kg m−2 a−1 for the average rate of snow accumulation upon the grounded ice sheet of Antarctica.
