A new approach is needed in soil tillage practice. The important achievements of this are the recognition of the risk – poor tillage practices, poor soil quality, soil state defects, and climate extremes etc. – the need for the development of risk reduction, prevention, remediation and maintenance of the favorable soil state. In this paper 13 main soil state defects are listed, to which the prevention and improving tasks are also commented. In the second part of the paper the most important soil tillage tasks are summarized in 30 sections and realization of these points may promote the implementation of precision plant production.

Abstract. This article investigates the implementation of disaster risk reduction education for children in Indonesia. In the last decade, education programmes related to this subject have been promoted as capable of reducing disaster losses and increasing resilience, based on several studies that have identified positive outcomes. Therefore, it is critical to evaluate and address any potential challenges that might impede their success. The article uses a case study in Jakarta, a rapidly growing megacity that is highly prone to disasters and natural hazards, especially floods and fires, to explore the scaling up and sustainability of disaster risk reduction in Indonesian schools. Based on previous studies, a new approach was developed for evaluating the implementation of education programmes related to these subjects. This study captured the perspectives of children, school personnel, and non-governmental organisations on the challenges of scaling up the implementation of disaster risk reduction education in schools. The study revealed seven key issues and suggests several policy recommendations to move forward. These key issues may also be apparent in many other developing and developed countries, and the suggested recommendations may well be applicable beyond Indonesia.

A new approach to the study of arterial baroreflexes was developed for use during the National Aeronautics and Space Administration Spacelab Life Sciences-1 Space Shuttle mission. This method holds promise as a means to characterize the vagal limb of human baroreflex responses comprehensively and efficiently.

AbstractA widely used tool in studying quasi-monoperiodic processes is the O–C diagram. This paper deals with the application of this diagram in minor planet studies. The main difference between our approach and the classical O–C diagram is that we transform the epoch (=time) dependence into the geocentric longitude domain. We outline a rotation modelling using this modified O–C and illustrate the abilities with detailed error analysis. The primary assumption, that the monotonity and the shape of this diagram is (almost) independent of the geometry of the asteroids is discussed and tested. The monotonity enables an unambiguous distinction between the prograde and retrograde rotation, thus the four-fold (or in some cases the two-fold) ambiguities can be avoided. This turned out to be the main advantage of the O–C examination. As an extension to the theoretical work, we present some preliminary results on 1727 Mette based on new CCD observations.

Previously we reported that tannic acid is a very effective fixative for proteins including polypeptides. Especially, in the cross section of microtubules, thirteen submits in A-tubule and eleven in B-tubule could be observed very clearly. An elastic fiber could be demonstrated very clearly, as an electron opaque, homogeneous fiber. However, tannic acid did not penetrate into the deep portion of the tissue-block. So we tried Catechin. This shows almost the same chemical natures as that of proteins, as tannic acid. Moreover, we thought that catechin should have two active-reaction sites, one is phenol,and the other is catechole. Catechole site should react with osmium, to make Os- black. Phenol-site should react with peroxidase existing perhydroxide.
