Research has found evidence for recent contamination of Lake Como, northern Italy, with chemicals banned in the EU since the 1970s. Levels of DDT and PCBs in sediment, aquatic microorganisms and fish were examined. The results suggest glacial meltwater as a source for renewed DDT contamination and show recent contamination of fish above safe levels. The findings demonstrate the need for continued monitoring of persistent organic pollutants in European waters.

The present invention provides polymerization processes utilizing an ansa-metallocene catalyst system for the production of olefin polymers. Polymers produced from the polymerization processes have properties that vary based upon the presence or the absence of hydrogen and/or comonomer in the polymerization process.

This invention concerns a creepage control system for locomotives that optimizes adhesion while minimizing wasted energy, rail/wheel wear and shock loading on the drive train. The basis of the invention is to always maintain a small but positive value of the slope of the wheel-rail adhesion creep curve (or differential of adhesion versus creep) for all traction axles of the locomotive through microprocessor control. The value of the differential of adhesion versus creep is used to define an operating window for control and operation of motors continually in the optimum domain when high adhesion is demanded. When, due to a sudden increase in rail contamination, the value of the control function becomes negative, the microprocessor control reduces the generator excitation in stages until the function becomes positive and inside the operating window again. The microprocessor controls a rail cleaning system which is turned on or off depending on the cleanliness of the rail. It also controls a rail sanding system which is turned on or off depending on the magnitude of wheel creep.

The adhesion between a locomotive drive wheel and supporting rail can be substantially increased by application of a powder mixture that contains a hard particle constituent preferably including alumina, a soft particle constituent preferably including titania, and an iron oxide constituent. The mixture may be in the form of a dry powder, a paste with water or alcohol vehicle, or a metal composite that includes the powder.

An apparatus (40,60) for aligning a rail conditioning system, such as a sanding system or a compressed air snow removal system of a locomotive. A source of light (50,70) is removeably and unmovingly attached to a conduit (44,62) of the rail conditioning system to direct a beam of light (53) toward a rail (46) to verify a location of impingement (56) of a spray of rail conditioning material (45,66). The source of light may be a battery operated laser pointer, and it may be attached to a fixture (48,72) that is removeably secured to the conduit. The fixture may be attached over an outlet nozzle (42,62) of the conduit, or it may be threaded onto the conduit in place of the nozzle when the nozzle is removed for cleaning and inspection.

A method of dynamically controlling traction of a locomotive (V) having a plurality of axles (A1–A6) on each of which are mounted wheels (W) for moving the locomotive over a set of rails (R). A creep control signal (creep_n) is provided to a controller (TMTC) for each axle to move the locomotive over the rails, the creep control signal being a function of adhesion operation characteristics (tractive effort, torque, creep) for that axle. An advisory signal (ccc_n) combining values representative of the adhesion quality of the two axles is provided to the controller to maximize the tractive effort of the axle if the adhesion quality of the other axle is a maximum for the current rail conditions. This reduces the amount of time for the axle to attain its maximum tractive effort when rail conditions change.

A system and method for assessing a health and functionality of a locomotive friction modifying system wherein the locomotive has a friction modifying applicator associated with a wheel of the locomotive for applying a friction modifying agent to a rail on which the wheel is traversing. The system and method comprise a sensor detecting a predetermined operational condition of the locomotive. The system and method also comprise a controller associated with the sensor and responsive to input from the sensor determining a per unit creep of an axle of the locomotive. The controller also determines a tractive effort of the axle of the locomotive and determines a friction modifying applicator state for the applicator associated with the axle. The controller further compares the determined per unit creep of the axle, the tractive effort of the axle and the state of the friction modifying applicator associated with the axle to a predetermined value indicative of the health and functionality of the locomotive friction modifying system. The controller provides an indication of the health and functionality of the locomotive friction modifying system.

A method of manufacturing a power contactor from an existing contactor having a magnetic amplifier that comprises a blowout coil and a ferromagnetic core, and an arc chute for extinguishing an arc generated by opening the existing contactor under a current load is disclosed. The method includes removing a bolt assembly from the existing contactor and at least one side plate from the existing contactor. The method also includes removing the ferromagnetic core from the existing contactor.

Data representative of a train consist (the train consist comprising a plurality of locomotives and a plurality of cars) and data representative of a route for the train consist can be processed by a processor to automatically determine which locomotives in the train consist should be powered on and which locomotives in the train consist should be shut down for each segment of the route. The processor can make these determinations based on an analysis of the train consist data and the route data with respect to a plurality of considerations that affect train efficiency. Recommendations for locomotive startups and shutdowns in accordance with such automated determinations can then be presented to the train crew for the crew to use during train operations. It is believed that when train crews are in compliance with such recommendations, significant improvements in efficiency, particularly with respect to fuel consumption, can be achieved.

A distributed power (DP) control system is contained within a non-freight carrying intermodal container for communicating with and receive instructions and/or commands from a command system of a lead distributed power locomotive within a train. The container is configured to be provided on a car adjacent to a remote non-distributed powered (non-DP) locomotive provided within a length of the train. One or more connection hoses connect the distributed power control system within the container to the non-DP locomotive to control application of at least its brake system.

Disclosed is a system and method for decreasing airflow and improving ventilation within a tunnel, such as a railroad tunnel, including a path for movement of a vehicle (e.g., train) therethrough. The system has a plurality of air baffles mounted within the tunnel, each device comprising a body and a mounting device. Each mounting device positions each body inside and along the length of the tunnel between the entrance and the exit. The air baffles are configured to restrict airflow at least in part in a longitudinal direction of the tunnel, thereby increasing a relative difference between a vehicle speed and air speed in a tunnel annulus when the vehicle passes through the tunnel. The restriction (e.g., decrease) of airflow in the tunnel reduces the piston effect resulting from the vehicle or train passing through, thus reducing emissions and heat generated by the locomotives in the tunnel.

Amylin, a pancreatic hormone and neuropeptide, acts principally in the hindbrain to decrease food intake and has been recently shown to act as a neurotrophic factor to control the development of AP->NTS and ARC->PVN axonal fiber outgrowth. Amylin is also able to activate ERK signaling specifically in POMC neurons independently of leptin. To investigate the physiological role of amylin signaling in POMC neurons, the core component of the amylin receptor, calcitonin receptor (CTR) was depleted from POMC neurons using an inducible mouse model. The loss of CTR in POMC neurons leads to increased body weight gain, increased adiposity, and glucose intolerance in male knockout mice, characterized by decreased energy expenditure (EE) and decreased expression of uncoupling protein 1 (UCP1) in brown adipose tissue (BAT). Furthermore, a decreased spontaneous locomotor activity and absent thermogenic reaction to the application of the amylin receptor agonist were observed in male and female mice. Together, these results show a significant physiological impact of amylin/calcitonin signaling in CTR-POMC neurons on energy metabolism and demonstrate the need for sex-specific approaches in obesity research and potentially treatment.

OBJECTIVE

Incorporation of comorbidity burden to inform diabetes management in older adults remains challenging. High-sensitivity cardiac troponins are objective, quantifiable biomarkers that may improve risk monitoring in older adults. We assessed the associations of elevations in high-sensitivity cardiac troponin I (hs-cTnI) and T (hs-cTnT) with comorbidities and improvements in mortality risk stratification.

OBJECTIVE

Despite evidence of a relationship among obstructive sleep apnea (OSA), metabolic dysregulation, and diabetes, it is uncertain whether OSA treatment can improve metabolic parameters. We sought to determine effects of long-term continuous positive airway pressure (CPAP) treatment on glycemic control and diabetes risk in patients with cardiovascular disease (CVD) and OSA.
