Tight focusing with very small f-numbers is necessary to achieve the highest at-focus ***,tight focusing imposes strong demands on precise target positioning in-focus to achieve the highest on-target irradiance We describe several near-infrared,visible,ultraviolet and soft and hard X-ray diagnostics employed in a~10^(22)W/cm^(2)laser±plasma *** used nearly 10 J total energy femtosecond laser pulses focused into an approximately1.3-μm focal spot on 5±20μm thick stainless-steel *** discuss the applicability of these diagnostics to determine the best in-focus target position with approximately 5μm accuracy(i.e.,around half of the short Rayleigh length)and show that several diagnostics(in particular,3ωreflection and on-axis hard X-rays)can ensure this *** demonstrated target positioning within several micrometers from the focus,ensuring over 80%of the ideal peak laser intensity *** approach is relatively fast(it requires 10±20 laser shots)and does not rely on the coincidence of low-power and high-power focal planes.

AiM To determine the relationship between serum deprivation or serum levels and cell proliferation of human hepatoma SMMC 7721 cells. METHODS Human hepatoma SMMC 7721 cells were grown in RPMi 1640 supplemented with 10% fetal calf (FCS) in 5% CO 2 incubator at 37℃ for 24h , and culture media were replaced to serum free or different serum FCS levels (2 5%, 5%, 10%, 20% and 25%). Six h, 12h , 18h and 24h after the culture, the cells were incorporated TdR for 4h . At last TdR incorporation was detected with liquid scintillation counting. RESULTS DNA synthesis of SMMC 7721 cells could be sharply stimulated by short time (6h) serum deprivation (the cpm value of 3H TdR incorporation of cells in serum free was 39 32 fold higher than cells in 25% serum), and the incorporation of 3H TdR was negatively related to the serum levels. Longer time serum starvation ( 12h , 18h and 24h ) also greatly stimulated DNA synthesis, although the cpm value of 3H TdR incroporation was less than that in 6h serum deprivation. Morphology of cells cultured in different serum levels also showed significant difference. CONCLUSiONS Compared with other cell lines such as BEL7404 and Swiss 3T3, human hepatoma SMMC 7721 cells had different response to the serum deprivation. Short time serum deprivation could greatly stimulate DNA synthesis of human hepatoma SMMC 7721 cells. Precautions must be given to the changes of serum levels for the detection of growth factors and drugs using SMMC 7721 cells as a model.

in this paper, the nonlinear collapse of the BOHAi-8 pile foundation jacket platform has been analyzed. The ultimate load and collapse process of two computational models of the structure are given. One model is of fixed support whose length is eight times the pile leg diameter and the other considers the nonlinearity of the soil-pile interaction.

An analysis of the formation of karst and karst-suffosion forms on the territory of the West Kazakhstan region is presented in this paper. Numerous literary sources were used as the information database for the analysis of the relief features of the West Kazakhstan region. Evaluation of the morphometric features of the collapsed new formations on the basis of materials of our own field research is presented here for the first time. According to the research objectives there were defined localization places of the karst-collapsed phenomena where the reconnaissance field surveys were carried out. Survey points’ localization has been carried out by means of GPS system with the help of 12-channel GPS-receiver of Garmin eTrex model. Geoinformational technology, based on Mapinfo 9.5 and ArcGiS 9.2 packages was used for the building of the information and cartographic database. Original thematic maps compiled on the basis of the research results’ analysis have been obtained in this research. The features of the Caspian Basin’s karst landscapes, formed as a result of salt-dome tectonic manifestations (inder Mountains, Malaya Bogdo Mountain, Bish-Chokho hill) are described in this paper. The important elements of the Caspian Basin salt-dome landscapes are landforms of the karst origin from large karst depressions of the karst-tectonic origin to modern forms of the sulfate karst: sinkholes, wells, polje, knobs (“Kurgantau”), arches, caves and grottoes. Some karst formations have a non-salt-dome origin. Three areas with the collapsed forms that have the karst-suffosion origin have been identified (near Konyr village, Berezovka village and zh.natalap village). The mechanism of the sinkholes formation is due to the changes of the groundwater regime and the displacement of limestone eluvium as a result of active anthropogenic impacts. The sinkholes occurence near zh.natalap village, which is located near the Karachaganak oil and gas field, is probably due to the anthropogenic ini
