Agar-Gel Immunodiffusion Test for Rapid Identification of Pollock Surimi in Raw Meat Products

A test for the rapid identification of raw pollock surimi (TRIPS) was developed. This was an adaptation of previously developed field screening agar-gel immunodiffusion tests for speciation of meat products. It was specific for Alaska pollock surimi at 2% concentration and other surimis at higher concentrations, showed detectable sensitivity to surimi in meat at 2–4%, and was 100% accurate in detection in laboratory trials.     

Incentives, Routines, and Self-Command

Virtue, then, being of two kinds, intellectual and moral, intellectualvirtue in the main owes both its birth and its growth to teaching... while moral virtue comes about as a result of habit, whencealso its name is one that is formed by a slight variation fromthe word (habit).... Of all the things that come to us by nature we first acquirethe potentiality and later exhibit the activity... but the virtueswe get by first exercising them.... men become builders by buildingand lyre-players by playing the lyre; so too we become justby doing just acts, temperate by doing temperate acts, braveby doing brave acts. This is confirmed by what happens in states; for legislatorsmake the citizens good by forming habits in them, and this isthe wish for every legislator, and those who do not effect itmiss their mark, and it is in this that a good constitutiondiffers from a bad one.     

HOW THE PAST MATTERS: North American Cities in the Twentieth Century

ABSTRACT: The past matters because it affects the present, and we can make serious errors of judgment when we ignore this fact. In studying the past, however, we should try to view it in its own terms and not simply in the light of current concerns. This will not only make for better history, but may be useful in broadening the terms of contemporary debates. These themes are illustrated in terms of the twentieth-century North American city. The influence of the past, and the errors of judgment caused by ignoring its effects, can be seen in Toronto. There, in the postwar era, the health of the central city and the viability of public transit have been attributed to good planning and urban governance. In fact, these features are partly the unintended consequences of the way the urban area developed in the first half of this century. The limitations of viewing the past in terms of the present are illustrated by the way that scholars have allowed current concerns to shape our conception of cities in the first half of this century. For example, the sharp distinction of city from suburb and the search for the origins of the modern land development industry have narrowed our vision of urban areas before World War II. The case of housing policy indicates that this narrowing has not only distorted our view of the past, but also has compelled us to reinvent mechanisms of housing provision, such as cooperatives and self-help, that had been attempted decades ago and subsequently forgotten.     

EXITING ENERGY DISTRIBUTION IN HONEYDEW MELON IRRADIATED WITH A NEAR INFRARED BEAM1

Emitted intensity was measured at 15° increments from the incident beam and around the equator of a honeydew melon which was irradiated with a near infrared beam. Signal strength was adequate up to 75° to provide a usable spectrum for NIR analysis of internal tissue. A noisy but recognizable spectrum was obtained at 180°.     

Zymogen Activation in Pancreatic Endoproteolytic Preparations and Influence on Some Whey Protein Hydrolysate Characteristics

A proteolytic preparation from porcine pancreas was isolated. Trypsin, chymotrypsin and elastase were characterized and their time-dependent stability at 37°C was studied. The supematant of a 30% (w/v) saturated ammonium sulfate precipitation of a pancreatic extract (30S) was developed to pilot-scale level. The influence of zymogen activation time on molecular characteristics of whey protein hydrolysates produced by 30S and the commercial pancreatic preparation Corolase PP were compared. Amino acid analysis and gel permeation chromatography were used to characterize lactalbumin hydrolysates produced. Physicochemical characteristics of whey protein hydrolysates could be altered by manipulation of zymogen activation conditions in pancreatic proteinase preparations to be used during subsequent protein hydrolysis.
