Critical Times

In the spring and early summer of 1953, three cattle herds in south Queensland were dipped in acaricides at intervals such that few or none of the cattle ticks (Boophilus microplus) attacking to the animals between dippings reached maturity. This was continued until the tick larvae hatching in the pastures in spring were greatly depleted in numbers, but was discontinued before they were exterminated, to avert the danger of the cattle losing their immunity to redwater fever. Throughout the rest of the summer and the early autumn these cattle were lightly infested, and required dipping relatively infrequently. On the other hand, on a property where early, intensive dipping had not been carried out, very heavy infestations of ticks were present throughout the summer and autumn in spite of monthly dippings. This procedure of relating times of dipping to the ecology of the tick has been termed "strategic dipping". In the 1954-55 season, results obtained by intensive spring and early summer dipping were not comparable with those of the 1953-54 season. This appeared to be attributable principally to delayed or relatively ineffective dippings at critical times. Effective application of strategic dipping, as during the 1953-54 season, would reduce the need for acaricidal treatment of the cattle in the summer months when dipping is likely to be delayed by rainy periods.

Effect Of Age

Three hundred and fifty Border Leicester X Merino ewes, born March-April 1961, were drafted to two flocks, A and B. Flock A only was joined with rams on February 14, 1962. Subsequently both flocks were joined in November or December each year from 1962 to 1965. The flocks were depastured together on all occasions except for joining and lambing of flock A in 1962. There were negligible differences, between the flocks, in ewe deaths, wool cut, lambs born and reared, lamb birth weight and lamb carcase weight for the mean for the four years or in each of the years 1963 to 1966. Meat production in flock A was increased by 12 kg per ewe as a result of the extra lambing. On the other hand, 3 per cent of the ewes of flock A died in 1962 but no deaths occurred in flock B. Joining when 10-11 months old in early autumn did not disrupt the practice of joining when 20-21 months old in early summer, and, in the experiment, was the most profitable procedure.

The Us

In the last two decades the comparative analysis of race relations in the U.S.A. and Brazil has been based on a conventional wisdom. It is the corollary of a larger conventional wisdom in the study of comparative race relations. The thesis is that systems of race relations in the Western Hemisphere are primarily of two types: bi-racial and multi-racial. The distinction is normally spelled out as follows. The U.S.A. is a prime example of a bi-racial system. In the prevailing logic of the US legal and social structure, individuals have historically been either black or white. In Brazil, on the other hand, there has been a spectrum of racial distinctions. At a minimum, Brazilian social practice has recognised white, black and mulatto. At a maximum, the phenotypical distinctions have become so refined as to defy analysis, or effective application for those who would discriminate.

To study the tick and tick borne protozoan diseases of livestock in the hilly areas of Bangladesh, an attempt was made to collect tick and blood samples from cattle, goat and gayal (Bos frontalis) from different areas of the three hill districts. In this study, two species of ticks namely, Boophilus microplus (92%) and Amblyomma testudinarium (21.6%) and two species of blood protozoa like Babesia bigemina (16.63%) and Anaplasma marginale (14.94%) were recorded. Seasonal prevalence of ticks was highest in summer (97%) in comparison to rainy (95%) and winter (86%) season. On the other hand, the seasonal prevalence of blood protozoa was highest in rainy season (45.45%) in comparison to summer (27.87%) and winter (16.55%). Again, animals aged more than 2 (two) years of age (52%) found to be more susceptible to blood protozoan diseases than animals aged between 1-2 years of age (33.97%). But none of the animals under one year of age were found to be infected with blood protozoan diseases. DOI: http://dx.doi.org/10.3329/ijarit.v1i1-2.13934 Int. J. Agril. Res.

Sudden Rise

AbstractWe have developed a model for theH2OandOHevolution in a comet outburst, assuming that together with the gas, a distribution of icy grains is ejected. With an initial mass of icy grains of 108kg released, theH2OandOHproductions are increased up to a factor two, and the growth curves change drastically in the first two days. The model is applied to eruptions detected in theOHradio monitorings and fits well with the slow variations in the flux. On the other hand, several events of short duration appear, consisting of a sudden rise ofOHflux, followed by a sudden decay on the second day. These apparent short bursts are frequently found as precursors of a more durable eruption. We suggest that both of them are part of a unique eruption, and that the sudden decay is due to collisions that de-excite theOHmaser, when it reaches the Cometopause region located at 1.35 × 105kmfrom the nucleus.

Transmission Microscope

We have become accustomed to differentiating between the scanning microscope and the conventional transmission microscope according to the resolving power which the two instruments offer. The conventional microscope is capable of a point resolution of a few angstroms and line resolutions of periodic objects of about 1Å. On the other hand, the scanning microscope, in its normal form, is not ordinarily capable of a point resolution better than 100Å. Upon examining reasons for the 100Å limitation, it becomes clear that this is based more on tradition than reason, and in particular, it is a condition imposed upon the microscope by adherence to thermal sources of electrons.

Life beyond 1MeV – like life after 40 – is not too different unless one takes advantage of past experience and is receptive to new opportunities. At first glance, the returns on performing electron microscopy at voltages greater than 1MeV diminish rather rapidly as the curves which describe the well-known advantages of HVEM often tend towards saturation. However, in a country with a significant HVEM capability, a good case can be made for investing in instruments with a range of maximum accelerating voltages. In this regard, the 1.5MeV KRATOS HVEM being installed in Berkeley will complement the other 650KeV, 1MeV, and 1.2MeV instruments currently operating in the U.S. One other consideration suggests that 1.5MeV is an optimum voltage machine – Its additional advantages may be purchased for not much more than a 1MeV instrument. On the other hand, the 3MeV HVEM's which seem to be operated at 2MeV maximum, are much more expensive.

Summary: My comment is basically restricted to the situation in which less-able students find themselves and refers only to literature in German. From this point of view I am basically able to confirm Marsh's results. It must, however, be said that with less-able pupils the opposite effect can be found: Levels of self-esteem in these pupils are raised, at least temporarily, by separate instruction, academic performance however drops; combined instruction, on the other hand, leads to improved academic performance, while levels of self-esteem drop. Apparently, the positive self-image of less-able pupils who receive separate instruction does not bring about the potential enhancement of academic performance one might expect from high-ability pupils receiving separate instruction. To resolve the dilemma, it is proposed that individual progress in learning be accentuated, and that comparisons with others be dispensed with. This fosters a self-image that can in equal measure be realistic and optimistic.

Abstract. Two experiments examined the influence of stories on recipients’ self-perceptions. Extending prior theory and research, our focus was on assimilation effects (i.e., changes in self-perception in line with a protagonist’s traits) as well as on contrast effects (i.e., changes in self-perception in contrast to a protagonist’s traits). In Experiment 1 ( N = 113), implicit and explicit conscientiousness were assessed after participants read a story about either a diligent or a negligent student. Moderation analyses showed that highly transported participants and participants with lower counterarguing scores assimilate the depicted traits of a story protagonist, as indicated by explicit, self-reported conscientiousness ratings. Participants, who were more critical toward a story (i.e., higher counterarguing) and with a lower degree of transportation, showed contrast effects. In Experiment 2 ( N = 103), we manipulated transportation and counterarguing, but we could not identify an effect on participants’ self-ascribed level of conscientiousness. A mini meta-analysis across both experiments revealed significant positive overall associations between transportation and counterarguing on the one hand and story-consistent self-reported conscientiousness on the other hand.

Group Memberships

Abstract. Not all group memberships are self-chosen. The current research examines whether assignments to non-preferred groups influence our relationship with the group and our preference for information about the ingroup. It was expected and found that, when people are assigned to non-preferred groups, they perceive the group as different to the self, experience negative emotions about the assignment and in turn disidentify with the group. On the other hand, when people are assigned to preferred groups, they perceive the group as similar to the self, experience positive emotions about the assignment and in turn identify with the group. Finally, disidentification increases a preference for negative information about the ingroup.
