Piglets (L-1) from 13 litters farrowed by 1-year-old, first litter alcohol-consuming dams were evaluated for altered morphology, A second group of piglets (L-2) farrowed by 6 second litter ...alcohol-consuming dams also was evaluated. Mean litter size and birth weight for L-1 piglets were 4.85 and 602 +/- 152 g; mean litter size and birth weight for L-2 piglets were 2.00 and 478 +/- 168 g. Fetal mortality rates for L-1 and L-2 piglets were 15 and 25%, respectively. Anomaly rates observed in fetal deaths were 11 and 100% for L-1 and L-2 piglets, respectively. L-1 anomalies were macrocephaly, microphthalmia, necrosis of bowel, nonexternalization of penile tissue, unascended kidney and unilateral renal hypodevelopment. L-2 anomalies were anencephaly, microcephaly, nonfusion of cranial sutures, macrocephaly, microphthalmia, nonfusion of mandibles, cleft palate, imperforate cloaca, sydactyly and polydactyly.
This paper considers payload swing control of large, marine cranes using an active rider block tagline system (ARBTS). The contribution is the control system development and simulation comparison of ...the ARBTS approach to standard luff cranes without ARBTS. It is shown that the ARBTS control system off-loads boom actuation (luff) for ship motion cancellation. Thus, the boom can be used for its intended purpose of moving the load radially per the operator's command. For the simulation case considered, the maximum luff power decreases from 150 kW to 4 kW and the luff rope speed decreases from 0.9m/s to 0.02m/s. Application of this approach to existing offshore crane designs could increase their operational envelope, without increased power requirements or necessitating costly mechanical changes, permitting operations in rough sea conditions.
The authors found that platelet serotonin concentrations were significantly elevated in patients with chronic schizophrenia and in patients with bipolar major depressive disorder. High-affinity ...serotonin uptake was significantly reduced only in patients with bipolar major depressive disorder. Thrombin-induced release of serotonin from platelets in any patient group was not different from that of normal control subjects. Platelet serotonin storage in chronic schizophrenic patients was also not different from that in normal control subjects. These platelet findings could not be explained by age, sex, or medication variables. The authors suggest that the pharmacodynamics of platelet serotonin may be different in chronic schizophrenia than in bipolar major depressive disorder.

The showcase intelligent transportation system (ITS) project for the state of New Jersey, Route I-80-MAGIC (Metropolitan Area Guidance, Information, and Control) is taking shape along 72 miles of ...highway. The ITS is made up of multiple traffic surveillance and information networks controlled and monitored by a central computer system. Thirty-seven closed circuit television cameras provide visual coverage of the roadway to the New Jersey Department of Transportation operations personnel.
Based on Bremer et al. (2011) and Eckart et al. (2012) we report on simultaneous observations and modeling of the millimeter, near-infrared, and X-ray flare emission of the source Sagittarius A* ...(SgrA*) associated with the super-massive black hole at the Galactic Center. We study physical processes giving rise to the variable emission of SgrA* from the radio to the X-ray domain. To explain the statistics of the observed variability of the (sub-)mm spectrum of SgrA*, we use a sample of simultaneous NIR/X-ray flare peaks and model the flares using a synchrotron and SSC mechanism. The observations reveal flaring activity in all wavelength bands that can be modeled as the signal from adiabatically expanding synchrotron self-Compton (SSC) components. The model parameters suggest that either the adiabatically expanding source components have a bulk motion larger than v_exp or the expanding material contributes to a corona or disk, confined to the immediate surroundings of SgrA*. For the bulk of the synchrotron and SSC models, we find synchrotron turnover frequencies in the range 300-400 GHz. For the pure synchrotron models this results in densities of relativistic particles of the order of 10^6.5 cm^-3 and for the SSC models, the median densities are about one order of magnitude higher. However, to obtain a realistic description of the frequency-dependent variability amplitude of SgrA*, models with higher turnover frequencies and even higher densities are required. We discuss the results in the framework of possible deviations from equilibrium between particle and magnetic field energy. We also summarize alternative models to explain the broad-band variability of SgrA*.
