160 samples were collected from Hunan Province in June 2009.The samples were analyzed for HCH and DDT by ASE extraction technique and GC-MS method.The results showed that organochlorine pesticide residues were found widely in all samples,and the mean residues of HCH and DDT were 8.03 μg/kg and 36.26 μg/kg with a range of 0.20-17.89 μg/kg and 5.05-45.96 μg/kg.Compared with the other region,these residual contents were in medium leve1.Different functions of soil have different levels of OCPs residue,with the residue of HCH is highest in rice paddy land,with the residue of DDT is highest in cotton land.
Ellipsometric Measurement of Transverse Kerr Magneto-Optic Effects (1988)

Ellipsometry is a powerful technique for the experimental determination of optical constants of thin film materials. In this paper, a novel technique for accurate measurement of magneto-optic effects of the transverse Kerr effect is described. For thin film applications, magneto-optic effects manifest themselves as first order perturbations, making it difficult to accurately determine the magneto-optic constants of a given material.
Identification and Genetic Control of two Rabbit Immunoglobulin Allotypes at a Second Light Chain Locus, the <i>c</i> Locus (1969)

Abstract Cross immunization of rabbits of different strains with IgG of varying electrophoretic mobility resulted in production of two precipitating allo-antibodies, which identified two IgG immunoglobulin light chain allotypes, c7 and c21. The c7 and c21 allotypes segregate as if controlled by allelic genes; however, progeny data of a few families suggest that the genes may instead be closely linked, i.e., pseudoalleles. The b and c light chain loci of immunoglobulins are not closely linked. The c locus is not linked to other immunoglobulin loci, i.e., the a heavy chain or f Ig A loci, nor to other serum protein loci, the Lpq low density lipoprotein and the Mtz α2 macroglobulin loci.
Conceptual Design Report: Dynamic Laser Compression Experiments at the HED Instrument of European XFEL (2017)

Since the publication of the conceptual design report (CDR) for the High Energy Density Science (HED) instrument at the European XFEL in 2013, it has become clear that a community-wide discussion for shock and ramp compression experiments at the HED instrument is needed. The HED group at European XFEL and the Helmholtz International Beamline for Extreme Fields at the European XFEL user consortium (HIBEF UC) agreed to do this together. This CDR on dynamic laser compression experiments at HED was drafted prior to the Dynamic Laser Compression workshop that was held on 12–14 September 2016 at European XFEL, where the CDR served as an outline for the presentations. Both the CDR drafting and the workshop programme were organized by Malcolm McMahon (for the HIBEF UC) and Ulf Zastrau (for European XFEL). An international team of contributing authors assembled this CDR and presented it to the entire community at the workshop.
Angiotensin II amplification of alpha-adrenergic vasoconstriction: role of receptor reserve. (1988)

Angiotensin II (Ang II) is known to enhance the vasoconstrictor response to norepinephrine (NE). In the present study, this interaction was investigated using isolated rabbit femoral artery rings mounted in tissue baths for the measurement of isometric contraction. Exposure to 3 x 10(-10) M Ang II caused a contraction that was less than 5% of the maximal response to NE. In the presence of Ang II, the NE dose-response curve shifted to the left twofold and the maximal response was not changed. The calcium channel antagonist nifedipine, 1 x 10(-7) M, caused a modest inhibition of the response to NE in either the presence or absence of Ang II. In contrast, nifedipine abolished the leftward shift of the NE dose-response curve caused by Ang II. Femoral arteries were pretreated with benextramine to cause partial alpha-adrenoceptor inactivation. The maximal contractile response to NE in these tissues was between 20% and 40% of that in control vessels, indicating that alpha-adrenoceptor reserve had been eliminated. In benextramine-pretreated vessels, the presence of 3 x 10(-10) M Ang II caused a modest leftward shift of the NE dose-response curve but increased the maximal responses to all NE concentrations by 200% to 800%. Nifedipine caused a modest inhibition of the response to NE in the absence of Ang II. In contrast, the enhanced response to NE in the presence of Ang II was nearly abolished. These results support our conclusions that 1) Ang II enhances the vasoconstrictor response to alpha-adrenergic stimulation, 2) the magnitude of enhancement is greater under conditions of reduced alpha-receptor reserve, and 3) calcium channel activation plays a major role in the amplified response.
Bioavailability, Skin‐and Nailpenetration of Topically Applied Antimycotics* (1982)

Summary: The penetration and permeation of econazol, oxiconazol and dimethylmorpholinohydrochlorid in the human skin and nails have been performed using the measurement of radio labelled substances (C 14 ≅ 250 μCi/ml) in vitro (penetration chamber) and in vivo. The penetration of the antimycotics inside the horny layer of the skin and the layers of the nail (10 μg/ml) ist sufficient enough to inhibit the growth of fungi by fungistatic mechanism. DMSO increases the penetration rate into the nail plate. Antimycotics solved in tinctures show a better penetration into the nails than the ointments which have advantages in penetrating the skin. The small fungicid effect and low dose in the deeper nails explains the long time topical treatment necessary at least for 6 months respectively the moulting process of the nail keratin.
A Novel Satellite Mission Concept for Upper Air Water Vapour, Aerosol and Cloud Observations Using Integrated Path Differential Absorption LiDAR Limb Sounding (2012)

We propose a new satellite mission to deliver high quality measurements of upper air water vapour. The concept centres around a LiDAR in limb sounding by occultation geometry, designed to operate as a very long path system for differential absorption measurements. We present a preliminary performance analysis with a system sized to send 75 mJ pulses at 25 Hz at four wavelengths close to 935 nm, to up to 5 microsatellites in a counter-rotating orbit, carrying retroreflectors characterized by a reflected beam divergence of roughly twice the emitted laser beam divergence of 15 µrad. This provides water vapour profiles with a vertical sampling of 110 m; preliminary calculations suggest that the system could detect concentrations of less than 5 ppm. A secondary payload of a fairly conventional medium resolution multispectral radiometer allows wide-swath cloud and aerosol imaging. The total weight and power of the system are estimated at 3 tons and 2,700 W respectively. This novel concept presents significant challenges, including the performance of the lasers in space, the tracking between the main spacecraft and the retroreflectors, the refractive effects of turbulence, and the design of the telescopes to achieve a high signal-to-noise ratio for the high precision measurements. The mission concept was conceived at the Alpbach Summer School 2010.
Fast volumetric visual hull computation (2011)

Silhouette-based reconstruction techniques using multiple wide-baseline camera set-ups are popular building blocks to generate models of temporal human action. This contribution reviews visual hull computation algorithms. In particular we focus on the class of volumetric-based algorithms. We identify different processing strategies based on hierarchical, octree-based processing and suggest a new dynamic strategy that can significantly minimise the computational effort. The techniques discussed are evaluated with synthetic and real data sets. The savings demonstrated in computations on the real test sequences are in the order of a factor six on a 512×512×512 volumetric resolution.
Difference frequency generation in a ZnGeP2 crystal pumped by a large aperture periodically poled MgO:LiNbO3 optical parametric system (2007)

Defective Ristocetin Aggregation Not Attributable to a Von Willebrand or Bernard-Soulier Type Defect (1977)

In von Willebrand’s disease the absence of platelet aggregation by ristocetin has been correlated with abnormalities in the von Willebrand factor (VIIIVWF), while in the Bernard-Soulier syndrome (BSS) a platelet membrane defect involving surface glycoproteins has been reported. During a 3 year period an absence of platelet aggregation induced by ristocetin was observed in a 53 year old Caucasian man with enlarged spleen, normal platelet count and eosinophilic leukaemia. The platelets react normally with collagen and ADP but the aggregation induced by thrombin and bovine VIIIVWF were reduced. The patient’s platelets were well agglutinated by an antibody reacting with a component absent in the BSS. The bleeding time, VIII levels, platelet adhesion to subendothelium (rabbit aorta) were normal. No abnormalities were detected in the surface glycoproteins as studied by SDS Polyacrylamide gel electrophoresis however the platelet sialic acid content was slightly reduced. It is concluded that an abnormality additional to those previously described may be the course of the defective ristocetin induced platelet aggregation in this patient.
PSYLLIUM HUSK AS A RETARDANT POLYMER FOR BUCCAL FILMS (2009)

The aim of present study was to evaluate buccal mucoadhesive films for controlled release of chlorhexidine to treat oral Recurrent Aphtous Stomatitis (RAS). Mono-layered mucoadhesive buccal films, containing 5 mg chlorhexidine base for local delivery to the oral cavity, were formulated by C.S.E. technique. A number of different bioadhesive and film-forming semi-synthetic and natural polymers, such as SCMC, HPMC and also Psyllium husk, as novel mucoadhesive agent opportunely treated, was evaluated for comparison; PEG was used as a plasticizer It was possible to change the amount of these excipients to modulate the mucoadhesive effect. The film formulations were characterized in terms of drugs content, morphology surface and drug release behavior (to maintain the salivary concentration of the drug above the MIC against C. albicans for a prolonged period of time). All the prepared buccal bioadhesive films were found to be satisfactorily good in terms of elasticity, flexibility and provided an in vitro controlled release of drug and particularly when chlorhexidine was incorporated in psyllium-extracted/SCMC-based film. In the presence of Psyllium husk the drug release was delayed due to slow swelling of this polymer, showing prolonged zero-order release.
Atomic resonance interaction in dielectric media (2004)

A theory is presented for the retarded resonance interaction in dielectric media between a ground state atom and an excited atom. We demonstrate in the retarded limit large deviations compared to earlier incorrect evaluations of this important quantity.
Design study status of compact containment BWR (2006)

The reactor concept considered in this paper has a relatively mid/small power output, a compact containment and a simplified BWR configuration with comprehensive safety features. The Japan Atomic Power Company has been taking initiative in developing the concept of the Compact Containment Boiling Water Reactor (CCR). The CCR., which is being developed with matured BWR technologies together with innovative systems/components, is expected to prove attractive in the world energy markets due to its flexibility in regard to energy demands and site conditions, its high potential for reducing investment risk and its safety features facilitating public acceptance. The flexibility is achieved by CCR's relatively mid/small power output of 400 MWe class and capability of long operating cycle (refueling intervals). CCR is expected to be attractive from view point of investment due to its simplification/innovation in design such as natural circulation core cooling with the bottom located short core, upper entry control rod drives (CRDs) and simplified safety system with high pressure resistible containment concept. The natural circulation core eliminates recirculation pumps and the maintenance of such pumps. The upper entry CRDs enable a simplified safety system followed by in-vessel retention (IVR) capability with the compact primary containment vessel (PCV). The safetymore » features mainly consist of large water inventory above the core without large penetration of RPV below the top of the core height, passive cooling system by isolation condenser (IC). The large inventory increases the system response time in the case of design-base accidents, including loss of coolant accidents. The IC suppresses PCV pressure by steam condensation without any AC power. Cooling the molten core inside the RPV if the core should be damaged by loss of core coolability could attain the IVR. Further core design study has been carried out taking into account compact reactor size and reduction of fuel bundles and CRDs. The feasibility of CCR safety system has been confirmed by LOCA analysis. The Compact Containment Boiling Water Reactor (CCR) has the possibility realizing both an economical and a safe small reactor through application of a simplified system and compact PCV.

An empirical analysis of instruction repetition (1998)

We study the phenomenon of instruction repetition, where the inputs and outputs of multiple dynamic instances of a static instruction are repeated. We observe that over 80% of the dynamic instructions executed in several programs are repeated and most of the repetition is due to a small number of static instructions. We attempt understand the source of this repetitive behavior by categorizing dynamic program instructions into dynamic program slices at both a global level and a local (within function) level. We observe that repeatability is more an artifact of how computation is expressed, and less of program inputs. Function-level analysis suggests that many functions are called with repeated arguments, though almost all of them have side effects. We provide commentary on exploiting the observed phenomenon and its sources in both software and hardware.
CAPSULE ENDOSCOPY IN THE EMERGENCY ROOM FOR ACUTE NON HEMATEMESIS GASTROINTESTINAL BLEEDING (2004)

Purpose: For more than 30 years, the first step in the management of acute gastro-intestinal bleeding (AGIB) has been upper endoscopy (EGD) and colonoscopy (COL). In the majority of patients bleeding has already stopped by the time the procedure is performed thereby reducing diagnostic accuracy. We conducted a pilot study to obtain preliminary information on whether CE can improve management of AGIB Methods: The study was performed prospectively in a community teaching hospital with 30,000 emergency room visits per year. 24 patients were randomized to either early [CE in the emergency room before conventional investigations] or late [CE after conventional work up completed] in a 2: 1 ratio. Diagnostic information from the early CE was provided to the attending physician as soon as possible. Additional work up was performed at the discretion of the attending physician. Results: Of the 138 patients screened over a 6-month period, 24 met our inclusion criteria (non-hematemesis acute gastro-intestinal bleeding) and signed consent. On presentation to the ER, the two groups were similar in age sex, initial blood pressure, hematocrit, and use of anticoagulants, aspirin and non-steroidal anti-inflammatory drugs. 21/24 (88%) patients were on anti coagulants/anti-platelet agents. Within 24 hours of enrollment, 12/16 (75%) patients in the early CE group had a presumptive source of bleeding detected by CE (10/16), EGD (1/8), COL (1/4) vs. 3/8 (38%) patients detected by EGD (3/4), CE (0/0), COL (0/1) in the CE late group (p = 0.099). Excluding CE, patients in the early group had 18 (1.13 procedures per subject), patients in the late group had 13 (1.63 procedure per subject). Median time to presumptive diagnosis by any modality was 19 hours in the early CE group vs. 35 hours in the CE late group (p = 0.06). Overall, active bleeding was detected by CE in 13/24 (54%) patients, 2/17 (11%) by EGD and 0/13 (0%) by COL. CE provided minimal or no useful data in 4/24 (17%) because of failure to swallow the capsule (1) or gastric retention (3). Conclusions: In this pilot study, there was a trend to both a significant increase in detection and decrease in time to detection of a presumptive source of bleeding when CE was done early in the work-up for AGIB. The mean number of conventional procedures per subject was reduced by performing CE early in the evaluation of AGIB.
Light trapping in a 30-nm organic photovoltaic cell for efficient\n carrier collection and light absorption (2012)

We describe surface patterning strategies that permit high photon-collection\nefficiency together with high carrier-collection efficiency in an ultra-thin\nplanar heterojunction organic photovoltaic cell. Optimized designs reach up to\n50% photon collection efficiency in a P3HT layer of only 30 nm, representing a\n3- to 5-fold improvement over an unpatterned cell of the same thickness. We\ncompare the enhancement of light confinement in the active layer with an ITO\ntop layer for TE and TM polarized light, and demonstrate that the light\nabsorption can increase by a factor of 2 due to a gap-plasmon mode in the\nactive layer.\n

Thermostability and Ca<sup>2+</sup>Binding Properties of Wild Type and Heterologously Expressed PsbO Protein from Cyanobacterial Photosystem II (2005)

Oxygenic photosynthesis takes place in the thylakoid membrane of cyanobacteria, algae, and higher plants. Initially light is absorbed by an oligomeric pigment-protein complex designated as photosystem II (PSII), which catalyzes light-induced water cleavage under release of molecular oxygen for the biosphere on our planet. The membrane-extrinsic manganese stabilizing protein (PsbO) is associated on the lumenal side of the thylakoids close to the redox-active (Mn)(4)Ca cluster at the catalytically active site of PSII. Recombinant PsbO from the thermophilic cyanobacterium Thermosynechococcus elongatus was expressed in Escherichia coli and spectroscopically characterized. The secondary structure of recombinant PsbO (recPsbO) was analyzed in the absence and presence of Ca(2+) using Fourier transform infrared spectroscopy (FTIR) and circular dichroism spectropolarimetry (CD). No significant structural changes could be observed when the PSII subunit was titrated with Ca(2+) in vitro. These findings are compared with data for spinach PsbO. Our results are discussed in the light of the recent 3D-structural analysis of the oxygen-evolving PSII and structural/thermodynamic differences between the two homologous proteins from thermophilic cyanobacteria and plants.
The use of learning algorithms in ATM networks call admission control problem: a methodology (1996)

The call admission control (CAC) problem, one of the most fundamental in ATM networks, has yet to be solved. We use a novel stochastic estimator learning algorithm (SELA) to predict in real time if a call request should be accepted or not, for various types of traffic sources. The feedback the algorithm receives has been drawn from the efficient equivalent bandwidth approximation proposed by Guerin et al. (1991). The proposed scheme exhibits a remarkable statistical gain compared with other CAC schemes reported in the literature, without QOS deterioration. The paper contains a simulation study of its performance and discusses several possible ways in which this work could be extended.
Ylide von Heterocyclen, V [1]. I-, N-und S-Ylide des 2-Pyrons und 2-Pyridons / Ylides of Heterocycles, V [1]. I-, N-and S-Ylides of 2-Pvrones and 2-Pyridones (1983)

The reaction of the pyrone 1 a or the pyridones 1 b, c with iodosobenzene leads to the iodonium-ylides 2 which undergo thermal rearrangement to the 4-phenyloxy-3-iodo compounds 3. Reductive deiodination of 3 gives the 4-phenyloxy compounds 4. By acid catalyzed treatment with nucleophiles (such as pyridine, nicotinamide, isoquinoline and thiophane) the iodonium-ylides 2 can be converted into the corresponding N- and S-ylides 5. Reaction of 2 with concentrated HCl or HBr gives the 3-halogeno substituted compounds 6.
