Field tests of several formulations of DDT and heptachlor as black-fly larvicides were made in 1953 and 1954 in irrigation canals in Alberta. The objectives of these tests were 1: to investigate further the relationship between larvicide effectiveness and the suspended solids content of the water, and 2: to investigate the use of formulations containing either emulsifiers or finely-divided inorganic particles which might improve larvicide effectiveness in clear-water streams.

Judgments of the distance of an underwater target at various locations were obtained as a function of water-clarity. When the target was close to S, its distance was underestimated. Judgments changed to overestimation as the actual physical distance was increased. Estimates were invariably greater in turbid water than in clear water. These data resolve the apparent conflict between expectations from optical considerations and actual distance estimates made in natural waters.

The Relationship

Abstract A pilot-scale fourdrinier former has been developed for the purpose of investigating the relationship between retention and paper formation (features, retention aids, dosage points, etc.). The main objective of this publication was to present the R-F (Retention and formation)-machine and demonstrate some of its fields of applications. For a fine paper stock (90% hardwood and 10% softwood) with addition of 25% filler (based on total solids content), the relationship between retention and formation was investigated for a microparticulate retention aid (cationic polyacrylamide together with anionic montmorillonite clay). The retention-formation relationship of the retention aid system was investigated after choosing standardized machine operating conditions (e.g. the jet-to-wire speed ratio). As expected, the formation was impaired when the retention was increased. Since good reproducibility was attained, the R-F (Retention and formation)-machine was found to be a useful tool for studying the relationship between retention and paper formation.

The objective of the work is to establish the characterization of the auditory disability and its relationship with resilience at the Technical University of Manabí. The article shows a conceptual analysis related to the inclusion and social integration of disabled students. Based on the fact that the person with disabilities grows and develops in the same way as that of people without disabilities and what usually happens is that disabled people are rejected and discriminated against based on a prefabricated and erroneous conceptualization of these people. The results associated with the application of the SV-RES test prepared by the researchers are shown (Saavedra & Villalta, 2008b). Characterization of the auditory deficit is made in the students, and the limitations that derive from it are pointed out. We analyze the particularities related to communication with students who have a hearing disability and resilience in this type of student, where some personal highlights that in this sense constitute an example of resilience. Finally, the results related to the study of the relationship between students' hearing disability and the level of resilience dimensions are shown.

(BJ6.350)Those who discard their weapons and surrender their persons, I will let live. Like a lenient master in a household, I will punish the incorrigible but preserve the rest for myself.So ends Titus' address to the embattled defenders of Jerusalem in the sixth book of Josephus'Jewish War(6.328-50). It is the most substantial instance of communication between Romans and Jews in the work. Titus compares himself to the master of a household and the Jewish rebels to his slaves. Is this how we expect a Roman to describe empire? If not, what does it mean for our understanding of the politics of Josephus' history? The question is particularly acute given that this is not just any Roman but Titus himself: heir apparent and, if we believe Josephus, the man who read and approved this historical account. It is thus surprising that, while the speeches of Jewish advocates of submission to Rome such as Agrippa II (2.345-401) and Josephus himself (5.362-419) have long fascinated readers, Titus' speech has received little or no attention. Remarkably, it is not mentioned in any of three recent collections of essays on Josephus. This paper aims to highlight the rhetorical choices that Josephus has made in constructing this voice for Titus—particularly his self-presentation as master—and the interpretive questions these raise for his readers. It should go without saying that the relationship of this text to anything that Titus may have said during the siege is highly problematic. (Potentially more significant, but unfortunately no less speculative, is the question of how it might relate to any speech recorded in the commentaries of Vespasian and Titus that Josephus appears to have used as a source.) What we have is a Josephan composition that is embedded in the broader narrative of theJewish War.

Abstract Bernal, M., Stratoudakis, Y., Wood, S., Ibaibarriaga, L., Uriarte, A., Valdés, L., and Borchers, D. 2011. A revision of daily egg production estimation methods, with application to Atlanto-Iberian sardine. 2. Spatially and environmentally explicit estimates of egg production. – ICES Journal of Marine Science, 68: . A spatially and environmentally explicit egg production model is developed to accommodate a number of assumptions about the relationship between egg production and mortality and associated environmental variables. The general model was tested under different assumptions for Atlanto-Iberian sardine. It provides a flexible estimator of egg production, in which a range of assumptions and hypotheses can be tested in a structured manner within a well-defined statistical framework. Application of the model to Atlanto-Iberian sardine increased the precision of the egg production time-series, and allowed improvements to be made in understanding the spatio-temporal variability in egg production, as well as implications for ecology and stock assessment.

Underwater plate vibration and its associated noise are of interest for the analysis of ship structures, propeller blades, and other areas of underwater acoustics. In order to analyze the relationship between a plate vibrating underwater and the acoustic pressure in the near-field, optical interferometric holography, using a blue-green laser beam, was used to determine surface displacement for the vibrating plate, which was excited through a fluid-coupled system. Acoustic measurements of the same source were made in a water tower concurrently with the holography and later at a precision acoustic testing facility. This method permits prediction of underwater plate modal frequencies and shapes with high accuracy.

Recent discussions of the history of American communism have generated a good deal of controversy. A youthful generation of “new social historians” has combined with veterans of the Communist party to produce a portrait of the Communist experience in the United States which posits a tension between the Byzantine pursuit of the “correct line” at the top and the impulses and needs of members at the base trying to cope with a complex reality. In the words of one of its most skillful practitioners, “the new Communist history begins with the assumption that … everyone brought to the movement expectations, traditions, patterns of behavior and thought that had little to do with the decisions made in the Kremlin or on the 9th floor of the Communist Party headquarters in New York.” The “new” historians have focused mainly on the lives of individuals, the relationship between communism and ethnic and racial subcultures, and the effort to build the party's influence within particular unions and working-class constituencies. Overall, the portrait has been critical but sympathetic and has served to highlight the party's “human face” and the integrity of its members.

В XVIII в. на основании общего интереса к святыням Востока, а также единой тенденции для крупных монастырей изготавливать гравюры на память для паломников, многие греческие гравюры свидетели русско-афонских отношений попадают на территорию Российской Империи. Сохранились такие гравюры и в Церковноархеологического кабинете Московской духовной академии, собрание которых насчитывает 29 эстампов. Пять гравюр из этого собрания имеют надписи на греческом и на славянском языке. Надписи свидетельствуют о месте и времени создания гравюры, о граверах и заказчиках, являются источниками кратких исторических сведений. В статье приведены выявленные дополнительные факты об этих гравюрах, которые свидетельствуют о наличии церковных, экономических и политических отношений на базе культурных связей между Российской Империей и странами православного Востока. The Russ has always been supporting the relationship with the Orthodox Church of the East. As a result of these connections, we have a lot of icons and other gifts from The Mount Athos, The Saint Catherine’s Monastery and others holy places. There are five Greek engravings in the collection of The Museum of Church Archaeology at the Moscow Theological Academy, which have inscriptions in Greek and Slavic. These engravings were to be spread in Slavic countries. They are dated from the 17th to the 19th century. Some of them were made in Moscow. The images and the inscriptions of the engravings are the subject of a research presented in this article.
