Investigation of multiple solutions for gas cooled current leads and results of survey information on current leads

This paper is divided into two distinct sections. In the first section, we investigate the possible existence of multiple steady state solutions for a gas cooled lead. In the second section, we summarize calculated values of the runaway and recovery times for 31 current leads in use throughout the world.     

Cocaine decreases cortical cerebral blood flow but does not obscure regional activation in functional magnetic resonance imaging in human subjects

The authors used functional magnetic resonance imaging (fMRI) to determine whether acute intravenous (i.v.) cocaine use would change global cerebral blood flow (CBF) or visual stimulation-induced functional activation. They used flow-sensitive alternating inversion recovery (FAIR) scan sequences to measure CBF and blood oxygen level-dependent (BOLD) sensitive T2* scan sequences during visual stimulation to measure neuronal activation before and after cocaine and saline infusions. Cocaine (0.6 mg/kg i.v. over 30 seconds) increased heart rate and mean blood pressure and decreased end tidal carbon dioxide (CO2). All measures returned to baseline by 2 hours, the interinfusion interval, and were unchanged by saline. Flow-sensitive alternating inversion recovery imaging demonstrated that cortical gray matter CBF was unchanged after saline infusion (-2.4 +/- 6.5%) but decreased (-14.1 +/- 8.5%) after cocaine infusion (n = 8, P < 0.01). No decreases were detected in white matter, nor were changes found comparing BOLD signal intensity in cortical gray matter immediately before cocaine infusion with that measured 10 minutes after infusion. Visual stimulation resulted in comparable BOLD signal increases in visual cortex in all conditions (before and after cocaine and saline infusion). Despite a small (14%) but significant decrease in global cortical gray matter CBF after acute cocaine infusion, specific regional increases in BOLD imaging, mediated by neurons, can be measured reliably.     

What does Goodfellow's classic analysis tell researchers today?

Discusses the significance of L. D. Goodfellow's (see record 1939-01413-001) interpretation of the Zenith Radio experiments in telepathy. Goodfellow provided a model for critiquing anomalous findings and paranormal claims, stimulated later statistical developments, and anticipated research on sequential patterns in guessing behavior and on contemporary work in cognitive biases.

DIRECT CATALYTIC CONVERSION OF METHANE TO HIGHER HYDROCARBONS

Using a plug-flow reactor we have been able to demonstrate the conversion of pure methane gas to liquid hydrocarbons via the intermediate formation of methanol. The reaction Was carried out at an intermediate pressure (about 20 atm) and moderate temperature (about 400°C). In the first stage of the reactor methane and oxygen react to produce methanol. In the second stage the methanol was converted by HZSM-5 catalyst to a mixture of hydrocarbons. Analysis of the reaction products showed that all of the oxygen Was used in the reaction. Apart from the unconverted methane the product was composed of oxides of carboy water and C₃+ hydrocarbons. Interestingly, among the liquid hydrocarbons, aromatics were found to be the major constituents.     

Psychiatric consequences of "ethnic cleansing": clinical assessments and trauma testimonies of newly resettled Bosnian refugees

OBJECTIVE: The authors describe the psychiatric assessments and trauma testimonies of 20 Bosnian refugees of "ethnic cleansing" who have recently resettled in the United States. METHOD: Refugees referred from agencies managing refugee resettlement underwent systematic, trauma-focused, clinical interviews that included standardized assessment scales. RESULTS: The traumatic experiences of ethnic cleansing in these Bosnian refugees were genocidal in nature. The number of types of traumatic experiences correlated positively with age. Posttraumatic stress disorder (PTSD) was diagnosed in 65% of the refugees, and depressive disorders in 35%. PTSD severity scores were correlated with the number of types of traumatic events experienced. CONCLUSIONS: Ethnic cleansing has caused high rates of PTSD and depression, as well as other forms of psychological morbidity, in this group of resettled Bosnian refugees. The longitudinal sequelae of ethnic cleansing as a form of massive psychic trauma remain to be studied.
