Carbon-ammonia pairs for adsorption refrigeration applications : ice making, air conditioning and heat pumping
A thermodynamic cycle model is used to select an optimum adsorbent-refrigerant pair in respect of a chosen figure of merit that could be the cooling production (MJ m(-3)), the heating production (MJ m(-3)) or the coefficient of performance (COP). This model is based mainly on the adsorption equilibrium equations of the adsorbent-refrigerant pair and heat flows. The simulation results of 26 various activated carbon-ammonia pairs for three cycles (single bed, two-bed and infinite number of beds) are presented at typical conditions for ice making, air conditioning and heat pumping applications. The driving temperature varies from 80 degrees C to 200 degrees C. The carbon absorbents investigated are mainly coconut shell and coal based types in multiple forms: monolithic, granular, compacted granular, fibre, compacted fibre, cloth, compacted cloth and powder. Considering a two-bed cycle, the best thermal performances based on power density are obtained with the monolithic carbon KOH-AC, with a driving temperature of 100 degrees C; the cooling production is about 66 MJ m(-3) (COP = 0.45) and 151 MJ m(-3) (COP = 0.61) for ice making and air conditioning respectively; the heating production is about 236 MJ m(-3) (COP = 1.50)
INDUCTION OF BONE MARROW COLONY-STIMULATING ACTIVITY BY A FILTERABLE AGENT IN LEUKEMIC AND NORMAL MOUSE SERUM
1. Leukemic Swiss mice of ICR/Ha strain which had been injected at birth with a lymphoid-leukemia-inducing virus preparation yielded sera which produced elevations of serum colony-stimulating activity within 16 hr and significant plasma-LDH-enzyme elevation at 4 days when injected intraperitoneally into normal ICR/Ha Swiss mice. Colony-stimulating activity was assayed in vitro by the stimulation of hemopoietic colony formation by DBA/1 bone marrow cells. 2. The inducing agent in leukemic serum was passageable, filterable, sedimentable, and heat-, ether-, and UV-labile. 3. A similar agent was recovered from normal Swiss serum after blind serial passages through normal mice. 4. LDH elevating virus induced a similar elevation of serum colony-stimulating activity when injected at high titers, and cross-resistance was demonstrated between LDH virus and the passaged leukemic serum agent

Judicial and statutory definition of authority : selected case studies of the Burger court
Student willful misconduct is one of the major concerns of school officials. The loss of a day's Instruction because of student misconduct or because of discipline for misconduct impacts upon individual students, the school, and society. Teachers, administrators, and legislators have sought and continue to seek solutions to these problems. This study has investigated willful student misconduct and the punishments inflicted because of this misconduct. The researcher examined corporal punishment and exclusion from school as punishments for several acts of misconduct. The research included a close examination of eight cases decided by the Supreme Court of the United States while Warren Burger was Chief Justice. The purpose of this examination was to ascertain current school officials' authority over students as it was defined by the Burger Court

Considerable evidence exists that the human contribution to ocean noise has increased during the past few decades: human noise has become the dominant component of marine noise in some regions, and noise is directly correlated with the increasing industrialization of the ocean. Sound is an important factor in the lives of many marine organisms, and theory and increasing observations suggest that human noise could be approaching levels at which negative effects on marine life may be occurring. Certain species already show symptoms of the effects of sound. Although some of these effects are acute and rare, chronic sublethal effects may be more prevalent, but are difficult to measure. We need to identify the thresholds of such effects for different species and be in a position to predict how increasing anthropogenic sound will add to the effects. To achieve such predictive capabilities, the Scientific Committee on Oceanic Research (SCOR) and the Partnership for Observation of the Global Oceans (POGO) are developing an International Quiet Ocean Experiment (IQOE), with the objective of coordinating the international research community to both quantify the ocean soundscape and examine the functional relationship between sound and the viability of key marine organisms. SCOR and POGO will convene an open science meeting to gather community input on the important research, observations, and modeling activities that should be included in IQOE
