Pore water was collected from sediment cores from Holes 1202A and 1202D in the southern Okinawa Trough during Ocean Drilling Program (ODP) Leg 195. Because drilling at this site was completed only a few hours out of port during the end of the leg, whole rounds of sediment core 5 or 10 cm long were sealed and stored at ~3°C until pore water could be extracted from them during Leg 196, using a titanium squeezer designed by Manheim and Sayles (1974) and standard handling techniques (Shipboard Scientific Party, 2002, doi:10.2973/odp.proc.ir.195.103.2002).

During Leg 195 of the Ocean Drilling Program, Site 1202 was drilled in the subtropical northwestern Pacific Ocean beneath the Kuroshio (Black Current) between northern Taiwan and the Ryukyu Island Arc on the northern flank of the I-Lan Ridge at 1274 m water depth. The upper 110 m of the Site 1202 section, composed of dark grey calcareous silty clay, provide an expanded record of environmental changes during the last 28 kyr. The sediments were deposited at high sedimentation rates between 3.0 and 5.0 m/kyr and peak values of 9.0 m/kyr between 15.1 and 11.2 ka BP. Variations in the modes and sources of detrital sediment input, as inferred from sediment granulometry, mineralogy, and elemental XRF-scanner data, reflect changes in environmental boundary conditions related to sea-level changes, Kuroshio variability, and the climate-driven modes of fluvial runoff. The provenance data point to increased sediment supply from northwestern Taiwan between 28 and 19.5 ka BP and from East China sources between 19.5 and 11.2 ka BP. The change in provenance at 19.5 ka BP reflects increased fluvial runoff from the Yangtze River and strong sediment reworking from the East China Sea shelf in the course of increased humidity and postglacial sea-level rise, particularly after 15.1 ka BP. The Holocene was dominated by sediments that originated from rivers in northeastern Taiwan. For the pre-Holocene period prior to 11.2 ka BP, low portions of sortable silt (63-10 ?m) show that the Kuroshio did not enter the Okinawa Trough, because of low sea-level. In turn, high proportions of sortable silt and sediment provenance from northeastern Taiwan point to strong ocean circulation under the direct and persistent influence of the Kuroshio during the Holocene. The reentrance of the Kuroshio to the Okinawa Trough was heralded by two pulses in relative current strengthening at 11.2 and 9.5 ka BP, as documented by stepwise increases in sortable silt in the lower Holocene section. From a global perspective, environmental changes in the southern Okinawa Trough show affinities to climate change in the western Pacific warm pool with little influence of climate teleconnections from the North Atlantic realm, otherwise seen in many other marine and terrestrial palaeoclimate records from southeastern Asia.

The significance of the photoperiod, a well-known phenomenon with arthropods, for the development of Cyclops vicinus were studied in laboratory conditions. There are indications that the point of the development process (development of the eggs and proportion of sexes) can be influenced through the photoperiod.

The Mössbauer technique has been used to study the nuclear hyperfine interactions and lifetimes in W182 (2+ state) and W183 (3/2- and 5/2- states) with the following results: g(5/2-)/g(2+) = 1.40 ± 0.04; g(3/2- = -0.07 ± 0.07; Q(5/2-)/Q(2+) = 0.94 ± 0.04; T1/2(3/2-) = 0.184 ± 0.005 nsec; T1/2(5/2-) >̰ 0.7 nsec. These quantities are discussed in terms of a rotation-particle interaction in W183 due to Coriolis coupling. From the measured quantities and additional information on γ-ray transition intensities magnetic single-particle matrix elements are derived. It is inferred from these that the two effective g-factors, resulting from the Nilsson-model calculation of the single-particle matrix elements for the spin operators ŝz and ŝ+, are not equal, consistent with a proposal of Bochnacki and Ogaza.

The internal magnetic fields at the tungsten nucleus were determined for substitutional solid solutions of tungsten in iron, cobalt, and nickel. With g(2+) = 0.24 the results are: |Heff(W-Fe)| = 715 ± 10 kG; |Heff(W-Co)| = 360 ± 10 kG; |Heff(W-Ni)| = 90 ± 25 kG. The electric field gradients at the tungsten nucleus were determined for WS2 and WO3. With Q(2+) = -1.81b the results are: for WS2, eq = -(1.86 ± 0.05) 1018 V/cm2; for WO3, eq = (1.54 ± 0.04) 1018 V/cm2 and ƞ = 0.63 ± 0.02.

The 5/2- state of Pt195 has also been studied with the Mössbauer technique, and the g-factor of this state has been determined to be -0.41 ± 0.03. The following magnetic fields at the Pt nucleus were found: in an Fe lattice, 1.19 ± 0.04 MG; in a Co lattice, 0.86 ± 0.03 MG; and in a Ni lattice, 0.36 ± 0.04 MG. Isomeric shifts have been detected in a number of compounds and alloys and have been interpreted to imply that the mean square radius of the Pt195 nucleus in the first-excited state is smaller than in the ground state.

Tekst stanowi krytyczną rekapitulację refleksji filmoznawczej prowadzonej w Czechach i Słowacji a dotykającej problematyki tzw. ženskej otázki (kwestii kobiecej). Myśl feministyczna i genderowa pojawiła się w refleksji publicznej i naukowej dopiero po Aksamitnej Rewolucji, napotykając na wstrzemięźliwą i zdystansowaną reakcję środowisk naukowych i twórczych. Dotychczasowa niezbyt rozbudowana refleksja nad kwestiami kobiecymi w kinie czeskim i słowackim, reprezentuje wczesny etap feminizmu akademickiego. Czesko-słowackie women’s studies skupiają się na gromadzeniu wiedzy dotyczącej historii, kultury, życia społecznego i politycznego kobiet. W centrum swojego dyskursu sytuują analizę wizerunków kobiecych, przede wszystkim we wczesnym kinie, rozważania nad kategorią kobiecości, jej specyfiką i przeobrażeniami dokonującymi się w procesie historycznym. Tymczasem w dokonaniach kinematografii Czech i Słowacji coraz większą rolę odgrywają kobiety reżyserki. Współczesne kino kobiet jest tu wyraźnie dostrzegalnym w swojej specyfice jakościowej i ilościowej zjawiskiem artystycznym, który na razie pozostaje obszarem nieeksplorowanym w czesko-słowackiej myśli filmoznawczej ukierunkowanej feministycznie i genderowo.

In the fall of 1989, emergency excavation was undertaken in conjunction with restoration work at the John Brice II (Jennings-Brice) House, 18AP53. The exact date of construction for this brick home is problematic, and it was hoped that archaeological investigation could provide conclusive evidence to firmly establish the structure's date of construction. Excavation of one 5 X 5 ft. unit revealed the presence of 10 separate soil layers and four features of note, described in detail below. Unfortunately, no builders trench or similar feature by which we might date the house's construction was recovered. Future plans and possibilities for excavation at the property are outlined with the hopes of performing subsequent work at this rich site. We anticipate a focus on the arrangement and changes in use of the houselot, amassing evidence to support the presence of a vernacular garden on the property during the 18th century, as well as researching refuse disposal patterns, and clues to changing lifeways through the 18th century.
