The research was carried out in 2017-2019 at the experimental field of the North-east Federal Research Center in the nursery of ecological testing of promising potato hybrids. The aim of the study was to identify hybrids for creating a new potato variety with high early productivity and final yield, attractive appearance of tubers and a high degree of resistance to major potato diseases. As the object of research 8 potato hybrids created at the Falenskaya breeding station — FGBNU FANC of the North-East were used: 27-07 (165-00 x 282-97), 62-08 (9326-2 x Zhukovsky early), 90-09 (194-00 x 45-7-17), 109-11 (183-05 x Dina), 170-08 (Sierra x 93.14-99), 172-11 (59-6-33 x Lazar), 179-10 (Dina x 45-7-17), 455-08 (591m-62 x Dubrava). As a standard was used the Nevsky potato variety zoned in the territory of the Kirov region. The evaluation of potato hybrids was carried out according to the guidelines for the technology of potato selection process: phenological observations, plant productivity on the 65th day from planting, final yield. The numbers 90-09, 170-08 and 179-10 with an early yield of 16.4-17.2 t/ha, an adaptability coefficient higher than 1 and a high degree of resistance to late blight were distinguished by the set of features.

We describe a case of cutaneous Larva Migrans in an 8-year-old Caucasian girl. The lesion appeared ten days after a bath in the river in a valley in the north-east of Piedmont. The patient was successfully treated with Albendazole 400 mg daily for 5 days. Autochthonous cases are rare, particularly in northern Italy. Probably the high temperatures and the high degree of humidity favored by the climate changes to which Europe is subjected are favorable to the development of larvae. The diagnosis of cutaneous Larva Migrans should, therefore, be considered also in individuals who have not traveled in geographic areas at risk for the climate.

Triplicate samples of rockpool algae were collected at each of three tidal elevations (upper, mid and low) from four shores on the north-east coast of England. Two moderately exposed (Ravenscar, the exposed shore at Filey Brigg), and two moderately sheltered (Selwicks Bay, the sheltered shore at Filey Brigg) shores were sampled during one week of spring tides during June 1996. A total of 6866 individual ostracods comprising of 26 ostracod species were recovered from the algal samples. Some species showed significant differences in abundance with tidal elevation across the four shores, e.g. Hirschmannia viridis was significantly more abundant in the upper shore pools. Other species, e.g. Heterocythereisalbomaculata, showed no significant difference in abundance either with tidal elevation or between shores. Significant differences in abundance occurred between shores at a given tidal height in some species, e.g. Semicytherura nigrescens was absent from Selwicks Bay but abundant on the remaining shores. Other species had markedly disjunct distributions, e.g. Callistocythere badia only occurred in the exposed upper shore pools at Filey Brigg. Ostracods were significantly less abundant in the low shore pools. Cluster analysis showed that low shore samples had a high degree of similarity between the four shores whereas the upper and mid-shore samples clustered primarily to shore. A two-way ANOSIM indicated that there was a significant difference in assemblage similarity between the four shores and also between the different tidal elevations.

ABSTRACT:A very high prevalence (approximately 1/475 in 1985) of myotonic dystrophy (Steinert disease) is observed in the Saguenay region, which is located in the north-east part of the Province of Quebec. For various reasons, however, the literature on the subject generally associates a high degree of selective disadvantage with this gene, which seems to contradict the Saguenay data. Using a computerized regional population register, we have reconstituted patients' genealogies and family biographies. We have thus been able to study the origin of the gene and to compare the demographic behavior of patients and controls. On the whole, patients seem to be very little disadvantaged compared to controls, in terms of reproduction as well as of geographical and occupational mobility.

Abstract Sorting grids and square mesh panels are the two most-applied technical devices to supplement codend size- and species-selection in demersal trawls. In the Barents Sea gadoid fishery, the compulsory size-selectivity system comprises a mesh section with a sorting grid followed by a diamond mesh codend. We tested the size-selective performance of a new sorting section that comprised a sorting grid combined with a square mesh panel as a potential alternative for the grid sections currently in use. The new sorting section was shorter and therefore more maneuverable than the existing sorting grid sections. The investigation was carried out on cod and the bycatch species redfish. The grid was found to contribute to the largest proportion of fish release, and the release through the square mesh panel was low. But, the results showed that the grid was successful at guiding fish not escaping through the grid to a second selection process in the panel. However, the square mesh panel did not result on the intended release efficiency except for the smallest sizes of fish, most likely because the guiding angle of the grid and the square meshes in the panel used did not provide a suitable escape path for the desired size range of fish. Therefore, optimizing the mesh size/shape in the panel and/or the guiding angle for the grid potentially could lead to the desired selectivity pattern in the new sorting section.

SUMMARY An algorithm and software are developed for fast and accurate evaluation of the elements of the geomagnetic field represented in high-degree (>720) solid spherical harmonics at many scattered points in the space above the surface of the Earth. The algorithm is based on representation of the geomagnetic field elements in solid ellipsoidal harmonics and application of tensor product needlets. Open source FORTRAN and MATLAB realizations of this algorithm that rely on data from the Enhanced Magnetic Models 2015, 2017 (EMM2015, EMM2017) have been developed and extensively tested. The capabilities of the software are demonstrated on the example of the north, east and down components of the geomagnetic field as well as the derived horizontal intensity, total intensity, inclination and declination. For the range from −417 m under the Earth reference ellipsoid up to 1000 km above it the FORTRAN and MATLAB versions of the software run 465 and 189 times faster than the respective FORTRAN and MATLAB versions of the software using the standard spherical harmonic series method, while the accuracy is less than 1 nT and the memory (RAM) usage is 9 GB.

The article presents a study on the development and productivity of promising potato varieties of domestic selection in the conditions of the North-East of Kazakhstan. This may be since not all varieties when grown in specific climatic zones of Kazakhstan show the qualities declared by the originators of these varieties. Natural and climatic conditions are one of the determining factors, under the influence of which the yield potential of potato varieties is realized. On the basis of the results of the experience, there were identified non-raised varieties, which can be recommended for cultivation in the conditions of the region. Potato Nerli varieties yield characteristics were close to zoned in the area Axor, by the number of tubers in the bush variety ahead of Nerli on 11%, but the number of standard fraction Nerli exceeded zoned variety Axor by 13.6%. The Nerli potato variety can be recommended for cultivation in the conditions of the North-East of Kazakhstan.
