Counts were made before and after fixation of the numbers of fertilised and unfertilised ova recovered from 3 mated sows, 7 unmated sows and from 34 sows inseminated at varying times before and after the onset of heat.The percentages of fertilised ova for sows inseminated the day before heat (day — 1) on the first day of heat (day 0) the second day of heat (day 1) and the third day of heat (day 2) are respectively for unfixed and fixed ova: 7·1 and 9·8, day – 1 ; 55·9 and 68·8, day 0; 63·4 and 98·2, day 1; 20·1 and 15·2, day 2. No fertilised ova were recorded from unmated sows; the percentages for mated sows were 94·3 and 95·5.It is concluded that failure of fertilisation is likely to be the greatest source of loss of fertility in inseminations made before heat and late in heat.Most ova from sows inseminated on day — 1 and from sows inseminated in day 2 had no spermatozoa on the zona pellucida. A few ova from sows inseminated on day 2 had very large numbers of spermatozoa present.It is suggested that failure of the spermatozoa to reach the site of fertilisation rather than their loss of fertilising capacity is likely to be the cause of the low fertility of early inseminations.

Relevance: the reason for the development of complications in endodontic treatment is poor-quality instrumental treatment root canals.Aims: a study of the animicrobial action and clinical efficacy of high-frequency monopolar diathermocoagulation in the treatment of chronic forms of pulpitis.Materials and methods: 102 patients with various chronic forms of pulpitis were divided into three groups of 34 patients each. In the first two groups, high-frequency monopolar diathermocoagulation was used in endodontic treatment in different modes. In the third group, endodontic treatment was carried out without the use of diathermocoagulation (comparison group). The root canal microflora in chronic pulpitis in vivo was studied twice-before and after diathermocoagulation.Results: it was established that high-frequency monopolar diathermocoagulation in the effect mode is 3, power is 4 (4.1 W) and effect is 4, power is 4 (5.4 W) with an exposure time of 3 seconds, it has a pronounced antibacterial effect on all presented pathogenic microflora obtained from the root canals of the teeth.

ABSTRACT By means of chromatographic and spectrophotometric methods progesterone and a substance closely similar to 20β-hydroxy-pregn-4-ene-3-one has been detected in luteal tissue from non-pregnant and pregnant cows. In 21 animals quantitative measurements based on a method giving an average net recovery of 56 per cent showed that in pregnancy the average progesterone content in the corpus luteum reached a maximum in the third to fifth month, with low values before and after this period. For 6 nonpregnant cows, the average value was 20.2 μg/g tissue, which is considerably higher than previous values reported in the literature. The relation between these findings and the bovine dependence on a functional corpus luteum in pregnancy is discussed, and it is pointed out that more information about the metabolism of progesterone in cattle is highly desirable.

This chapter explores the archival texts of the Neo-Assyrian Empire and attempts to gauge the legal and economic position of slavery in Assyrian society. It shows that the Assyrians held a similar legal understanding of slavery to the Greeks, and knew also of the phenomenon of debt bondage. The chapter then moves on to consider the location of slavery in Assyrian society, showing widespread and significant levels of slave ownership among the Assyrian elite; however, relatively high slave prices prevented slave ownership from becoming a more widespread phenomenon. The third part of the chapter looks at the Assyrian countryside more broadly, and shows that despite often owning large numbers of slaves, members of the Assyrian elite more probably drew the bulk of their income from the exploitation of bound tenant farmers.

Compare And Contrast

Many evolutionary theorists have enthusiastically embraced human nature, but large numbers of evolutionists have also rejected it. It is also important to recognize the nuanced views on human nature that come from the side of the social sciences. This introduction provides an overview of the current state of the human nature debate, from the anti-essentialist consensus to the possibility of a Gray’s Anatomy of human psychology. Three potential functions for the notion of species nature are identified. The first is diagnostic, assigning an organism to the correct species. The second is species-comparative, allowing us to compare and contrast different species. The third function is contrastive, establishing human nature as a foil for human culture. The Introduction concludes with a brief synopsis of each chapter.

Punic Wars

This chapter provides a brief introduction to how the historiographical development of Roman studies, since mid-twentieth century decolonization, has altered our understanding of the developments which took place in North Africa following the destruction of Carthage in 146 bce. The reader is introduced to literary, epigraphic, and archaeological sources of evidence, which have traditionally been used to argue for either cultural change or continuity. After an initial examination of the immediate aftermath of the Third Punic War, Roman land appropriation and taxation, the focus is on sources of evidence usually described as “Punic,” “neo-Punic” or “Late Punic,” covering the spheres of municipal institutions, language use, and religious and funerary rituals. The vibrant multiculturalism and regional diversity of the Mediterranean and especially North Africa, both before and after the Roman conquest, is the dominant theme. This is used to shift emphasis away from grand explanatory paradigms based on essentialist identity categories, and toward a more nuanced picture of the complex and multivariate processes of cultural development and integration.

Two white sisters of Italian parentage in whom thalassemia-hemoglobin C disease was found, have been presented. This is the third report of such cases and the first in white individuals. This disease produces a microcytic anemia which is usually mild but which may be severe. Splenomegaly may or may not be present. The presence of large numbers of both microspherocytes and target cells in the blood smear should suggest the possibility of this diagnosis. Confirmatory evidence is found in studies of the blood of family members.

This is the third and final installment of Um Jabr's ““life story,”” earlier segments of which——on village life in pre-1948 Palestine and on the 1948 war and its aftermath——were published in JPS 138 (winter 2006) and JPS 140 (summer 2006). The current excerpts focus on Um Jabr's intense involvement in the prisoner issue that began when two of her sons were in Israeli jails. In particular, her activism took the form of organizing other women to visit prisoners from Arab countries who had no one to visit them on the twice monthly visits allowed. Um Jabr's 36,000-word ““life story”” was one of seven collected as part of an oral history project, as yet unpublished, carried out by Barbara Bill, an Australian who since 1996 has worked with the Women's Empowerment Project of the Gaza Community Mental Health Program, and Ghada Ageel, a refugee from al-Bureij camp now earning her Ph.D. at the University of Exeter in England. The women who participated in the project were interviewed a number of times during the first half of 2001; after the tapes were transcribed, the memories were set down exactly as they were told, the only ““editing”” being the integration of material from the various interviews into one ““life story.”” Um Jabr, who was in her early 70s at the time of the interviews, still lives in al-Bureij camp, where she has since 1950.

Flexible Instruments

This study used a mechanical test to evaluate the flexibility of instruments from the K3 (conicity 0.04) and the ProTaper Universal systems when they were new and after 5 uses in simulated canals. Five sets of instruments of each system were tested: K3 (15, 20, 25, 30, 35, 40 and 45) and ProTaper Universal (S1, S2, F1, F2, F3, F4 and F5). Each set of instruments was used to prepare a simulated canal and the same set of instruments was used 5 times (50 canals). The number of each subgroup represented the number of uses: 0 (control), 1, 3 and 5 uses. Before and after each use, the instruments were submitted to a mechanical flexibility test performed in a Versat 502 universal testing machine. Interactions between the instrument and the number of uses were analyzed by ANOVA and Tukey's test at a 5% level of significance. Instruments from both systems presented lower flexibility after the third use compared to the flexibility obtained after uses 0 and 1 (p<0.05), and maintained the same flexibility after the fifth use. The flexibility of instruments from the K3 system decreased with the increase of diameter, irrespective of the number of uses. Among the instruments from the ProTaper Universal system, the shaping files presented greater flexibility than the finishing files. F2 and F3 were the least flexible instruments, and F4 and F5 presented flexibility values similar to those of F1.
