The general aim of this research was to determine whether the cherry root cambium possesses similar water-stress adaptation abilities as the scion. Specifically, this study aimed to determine whether there is a shift in root xylem structure due to precipitation fluctuations and temperature increase during the growing season in two cherry species. Oblačinska sour cherry and European ground cherry roots with secondary structure were anatomically surveyed in detail, and correlated with meteorological conditions occurring during the vegetation when the roots were formed. Under environmental signals, both investigated species altered their radial root growth imprinting stops and starts in a cambial activity that resulted in the occurrence of intra-annual false growth rings. Changing environmental conditions triggered the shifts of large and small vessels throughout the false growth rings, but their size seemed to be mainly genetically controlled. Taking into consideration all the above, genotypes with moderate vessel lumen area—lesser or around 1200 μm2 in the inner zone, as well as no greater than 1500 μm2 in the outer zone—are presumed to be both size-controlling and stable upon the drought events. Thus, further field trials will be focused on the SV2 European ground cherry genotype, and OV13, OV32, and OV34 Oblačinska sour cherry genotypes.

SummaryThis paper describes the necessity of adapting the major classifications of mental disorders exemplified by the ICD-11 and the DSM-5 for the special needs of primary medical care. An earlier version of the classification – the ICD-10-PHC – is described, and the process of adapting it is described in detail. The new 28 item version of the classification is described, and the procedures to be adopted in the Field Trials to be held during 2013 are set out, together with the specific problems these field trials will address.

: The use of learning media is one of the critical success factors in higher education, therefore an educator must have innovation to use of learning media. The purpose of this research is to develop learning media based on the Inspiring Suit 8 on arbitration material courses of theoretical and practice for Volleyball 1 academic year 2018/2019 at IKIP Budi Utomo Malang. The existence of media will be a big successful support in learning process, so that students do not feel boredom because of the weaknesses of the lecturers, in which they are unable to provided good learning variation or even have difficulty in conveying or transferring knowledge. The research was descriptive qualitative design. The research subjects were students of Physical Education, Health, and Recreation Study Program who took volleyball theory and practice courses in the even semester academic year 2018/2019. The instruments used were the media expert review questionnaire, the learning expert questionnaire, and the trial analysis questionnaire. The questionnaire will be analyzed to see the feasibility of the developed media. Based on the data results review by media expert volleyball, media learning expert and field trials, it can be concluded that media developed is useful in learning process. In addition, it is used to provide independent motivation, which can be used in lesson for students.

Field trials were conducted in the wet seasons of 1997 and 1998 at Makurdi, Otukpo and Yandev in the Southern Guinea Savanna ecological zone of Nigeria to study the responses of ten soybean genotypes to intercropping. The experiment was laid out in a randomised complete block design. The genotypes TGX 1807-19F, NCRI-Soy2, Cameroon Late and TGX 1485-1D had the highest grain yield. All the Land Equivalent Ratio (LER) values were higher than unity, indicating that there is great advantage in intercropping maize with soybean. The yield of soybean was positively correlated with the days to 50% flowering, days to maturity, plant height, pods/plant and leaf area, indicating that an improvement in any of these traits will be reflected in an increase in seed yield. There was a significant genotype × yield × location interaction for all traits. This suggests that none of these factors acted independently. Similarly, the genotype × location interaction was more important than the genotype × year interaction for seed yield, indicating that the yield response of the ten soybean genotypes varied across locations rather than across years. Therefore, using more testing sites for evaluation may be more important than the number of years.
