AbstractOver the past 15 years, our knowledge of the interior of the Sun has tremendously progressed by the use of helioseismic measurements. However, to go further in our understanding of the solar core, we need to measure gravity (g) modes. Thanks to the high quality of the Doppler-velocity signal measured by GOLF/SoHO, it has been possible to unveil the signature of the asymptotic properties of the solar g modes, thus obtaining a hint of the rotation rate in the core (García et al. 2007, 2008a). However, the quest for the detection of individual g modes is not yet over. In this work, we apply the latest theoretical developments to guide our research using GOLF velocity time series. In contrary to what was thought till now, we are maybe starting to identify individual low-frequency g modes. . .

Abstract. We reconstructed the ventilation record of deep water at 2100 m depth in the mid-latitude western North Pacific over the past 25 kyr from radiocarbon measurements of coexisting planktic and benthic foraminiferal shells in sediment with a high sedimentation rate. The 14C data on fragile and robust planktic foraminiferal shells were concordant with each other, ensuring high quality of the reconstructed ventilation record. The radiocarbon activity changes were consistent with the atmospheric record, suggesting that no massive mixing of old carbon from the abyssal reservoir occurred throughout the glacial to deglacial periods.

The surfaces of the microlenses at the conical end-faces of optical fibers require high quality to keep the best performance of laser beam delivery. The polishing parameters play an important role to get the best quality of the microlenses. Most of the past researches study on the polishing parameters of flat surfaces. In this study, the polishing area of the conical end-face of the optical fiber is varied during fabrication. The relation between removed volume and removed thickness is built to determine the material removal rate. An experiment is carried out and the results show that the first two spinning turns are much effective for polishing under the parameters of the experiment.

The aim of the paper is to determine the scale of agricultural land conversion in gmina (municipalities) located in selected metropolitan areas of Poland. Analyses were conducted taking into account the location of agricultural land in relation to the core of metropolitan area and its suitability for agricultural production. The research has shown that in the metropolitan areas selected for analysis, agricultural land conversion in the period 1996–2014 was over twice as fast as the average for Poland, with the most land converted in the core of a metropolitan area, little less in the first zone of gmina around the core, and the least in gmina located on the outskirts of a metropolitan area. The hypothesis saying that the distance of a gmina from the core of the metropolitan area is a significant factor in the differences in conversion processes, and high quality of environmental conditions of agricultural production does not limit (in a significant way) the process of farmland abandonment has been positively verified.

AbstractThe Perseus cluster is the X-ray brightest cluster in the sky and with deep Chandra observations we are able to map its central structure on very short spatial scales. In addition, the high quality of X-ray data allows detailed spatially-resolved spectroscopy. In this paper I review what these deep observations have told us about AGN feedback in clusters, sloshing and instabilities, and the metallicity distribution.

Milking Machine

Advisory officers and milking machine manufacturers have, in the past, criticised scientists on the ground, it is claimed, that no attempt is made to describe developments associated with farming in terms which can be understood by intelligent laymen. This article deals with the specific problem of the effects of the milking machine on milk quality. It suggests one approach to the problem of machine design. There may well be other solutions which have not yet been explored. It is realised that the requirements for high quality milk production may contradict the needs of the farmer with a large herd who is short of labour. There is also the problem of mastitis. These aspects will be examined in later articles in the series, with the thought that, out of an up-to-date consideration of all the problems involved, a working solution will emerge which will be economical, efficient and available to New Zealand farmers.

The Human Condition

A complex and controversial novel, Atonement is at the core of a lively critical debate, opposing those who focus on the impossibility of Briony’s atonement – also in relation to the author’s atheist views – to those who conversely explore the redemptive quality of her “postlapsarian” painful self-fashioning. Far from concerning simply the destiny of a literary character, this debate has to do with the impact Postmodernist relativism has on both the conception of the human subject and the discourses of the past, from memory to history and fiction. Discarding any potentially nihilistic interpretations of Atonement as disempowering, this article delves into Ian McEwan’s multi-layered text in order to comprehend its ambivalences, its subtle investigation of the human condition, and its status as a postmemory novel reconnecting us to the events of World War Two.

History Learning

History learning should prioritize local wisdom values that grow in their respective communities. This is, so that future generations do not lose their identity and pride in their region. In learning local history, the next generation must know and understand what happened in the past in their society. This causes future generations to learn from their predecessors and be able to take local wisdom values. Therefore, local history material in history learning in senior high schools is vital. This study aimed to determine the use of local historical sources, teacher preparation in learning, the delivery process, and students' understanding of history learning. The form of this research is qualitative with a research strategy using case studies. The results showed that SMA N 1 Pontianak was better at utilizing local historical sources. This is because the quality of teachers and supporting facilities are of high quality. The SMA N 1 learning implementation plan at the design stage has also included local history materials. Then the delivery process in both schools shows that the teachers are good enough and creative and adjust to each school's conditions. Then the understanding of students in both schools to learn local history is good enough. This is due to students' interest in these materials.
