The study presented the history of the synthetic sheep lines BCP and SCP and the method by which they were created by the employees of the Department of Small Ruminant Breeding and Agricultural Advisory, University of Life Sciences in Lublin. The article additionally describes the role of these animals in sheep production and experimental research. Comprehensive analysis of the effects of breeding work in these populations, together with the results of scientific research using them as subjects, indicates that sheep of the synthetic universal prolific meat lines BCP and SCP are fully suitable for production of meat lambs in both intensive and extensive rearing conditions. Animals of both lines underwent experiments related to the genetic, physiological and environmental determinants of the level of reproductive and meat performance, which showed that these populations are well-suited for scientific experiments. According to the authors, in further selection work on the synthetic BCP and SCP lines greater focus should be placed on the percentage of reared lambs and the conformation of the dorsal part of the torso. They also indicated the need for monitoring of genetic variation due to the risk of increased inbreeding.

Scientific workflows and their supporting systems are becoming increasingly popular for compute-intensive and data-intensive scientific experiments. The advantages scientific workflows offer include rapid and easy workflow design, software and data reuse, scalable execution, sharing and collaboration, and other advantages that altogether facilitate “reproducible science”. In this context, provenance – information about the origin, context, derivation, ownership, or history of some artifact – plays a key role, since scientists are interested in examining and auditing the results of scientific experiments. However, in order to perform such analyses on scientific results as part of extended research collaborations, an adequate environment and tools are required. Concretely, the need arises for a repository that will facilitate the sharing of scientific workflows and their associated execution traces in an interoperable manner, also enabling querying and visualization. Furthermore, such functionality should be supported while taking performance and scalability into account. With this purpose in mind, we introduce PBase: a scientific workflow provenance repository implementing the ProvONE proposed standard, which extends the emerging W3C PROV standard for provenance data with workflow specific concepts. PBase is built on the Neo4j graph database, thus offering capabilities such as declarative and efficient querying. Our experiences demonstrate the power gained by supporting various types of queries for provenance data. In addition, PBase is equipped with a user friendly interface tailored for the visualization of scientific workflow provenance data, making the specification of queries and the interpretation of their results easier and more effective.

AbstractAfter briefly reconstructing the history of comparison both as a method of ‘comparing sciences’ in the 18th and 19th centuries and as an every-day phenomenon, the essay sets out to explore the historic and on-going debate on anthropological origins and features of comparing. By referring to different academic cultures – natural sciences, social sciences, humanities – the paper confronts insights and results of scientific experiments that test comparing practices of primates with Franz Kafka’s Report to an Academy. While the anthropological question still remains unresolved, the different cultures of science and literature reveal different aspects by laying bare the foundations of comparing processes.

Important Milestone

AbstractIn successfully carrying out a manned lunar landing and return, with both operational and technological objectives, the Apollo program made possible a variety of significant scientific experiments. This important milestone in the continuing quest for knowledge took the eyes, hands, and mind of man, as well as his instruments, to a new world. The activities of highest priority carried out by the astronauts, once the landing had been successfully completed, were to collect lunar material and data, emplace sophisticated experiments, and record man’s impressions and observations.In the missions ahead, scientific exploration of the Moon will be the principal goal. Unique features and sites on the Moon will be visited. New experiments, both on the lunar surface and in lunar orbit, will be carried out, as we probe the Moon’s past and attempt to unravel the early history of the Earth. In so doing, we will also be establishing and defining the possibilities and limitations of man as a space explorer as we extend his domain further in space.

Trees Outside Forest

Abstract Increasing environmental threats to agricultural production and the stability of ecosystems have been observed on the Polish lowlands since the 1970s. Several hundred million trees and shrubs have been planted on farmland, mostly along roads and with the involvement of public agencies, with a view to timber being produced, and soil erosion and the water deficit mitigated. On the basis of over 50 years of practical observations and scientific experiments, recommendations have been drawn up as regards the structural and spatial features of new tree planting outside forests that maximize environmental, production-related and social benefits. This paper gives a brief description of the history of the active establishment of woody vegetation across agricultural landscapes in Poland, along with best practices elaborated for this at several scientific centres.

Critical Resources

In the early twentieth century, the vernacular science periodical emerged as a key medium for building science-literate publics in colonial South Asia. This article argues that the Hindi science monthly Vigyan became a discursive laboratory for experiments with language, literary genres, narrative plots, and settings to create culturally grounded science lessons for Hindi readers in the mid-1910s. I focus on the writings of Prem Vallabh Joshi, a pandit, science graduate, and small town teacher, who experimented with distinct literary genres to create a sensibility for science – an experimental temper – amongst Vigyan’s readers. Through his strategic use of scientific experiments in the “history of” a particular branch of knowledge, detective mysteries, and the genre of the fictionalized dialogue, Joshi inducted colonial readers into experimental culture and global scientific modernity. As a reflexive participant in the ongoing confrontation between “Western” science and Hindu śāstra in colonial society, Joshi staged a fictional encounter between the experimental demonstration of the iconic air-pump and the textual authority of śāstra. This article examines the encounter between sastric commitments and scientific sensibilities and their conjoined mobilization in Vigyan in the era of linguistic nationalism. In this colonial vernacular publishing culture, the serial possibilities of the periodical and the history of science itself became critical resources in the ontological confrontations between experimental science and traditional authority.

The article proposes an investigation of the contributions of G. Simondon in the studies of Science and Technology. Leaving the contributions of cybernetics behind, Simondon investigates the processes of individuation, development and evolution of technology. According to his philosophy of machines, technical objects are contextualized both synchronically and diachronically. In contrast with other theoretical approaches of this problem, we emphasize that the interest of this author lies in the energetic determinism that is manifested in and outside technical objects. At last, we point out the contributions of this theoretical approach to contemporary studies on the history of scientific experiments.

The article deals with the concept of color in linguistic. There are opinions of scientists who analyzed the concept “shade”. The color must be seen from different points. The article presents the history of the color’s learning. There are some scientists’ points from the different countries. Linguists have opinion that the color in different languages may have the same meaning. There were many scientific experiments, which showed that the color can be a fixed lexeme and can have an alternative equivalent. Other linguists say that the color in different languages cannot have common features. The article emphasizes the need to focus on linguistic and cultural nuances. The color can reflect the culture of the country, man’s mental world. Some linguists underline that the color category is various. The article describes that the visual reception of people consists of the ability to recognize the color. It is impossible to say, what area of men’s interests can be without color. Particular attention is paid to the etymology of colors in the examples. There are many colors, which are very important in the German language.
