Alpha spectrometry in emergency preparedness

A study to assess the choice of science as a vocation and career, considering alpha spectrometry in emergency preparedness, was carried out. The development of a career or a vocation by any individual in the field of science could better be achieved through consolidated plan towards a goal. In this assessment, a number of required variables for developing skills by scientists for the future have been analyzed and considered to be essential in a strategic build-up to a career. Through the various fields of scientificradiation technology from their operation through to waste management, contamination measurement and other radiological analysis are identified to be very important. To make this approach more proficient, certain required variables for developing skills by scientists for the future have been elaborated in this study. Some of the requirements considered are; Education, Creativity, Culture, Employment, Finance and Governance. It was resolved that in evaluating the choice of a career, the Strengths, Weaknesses, Opportunities, and Threats (SWOT) analysis relating to the parameters (requirements) indicated above cannot be overemphasized in the buildup of a modern scientific career

Description of radiation conditions and evaluation of the date of ¹³⁷Cs release to the atmosphere using the radionuclide transfer model coupled with the forecasts by the mesoscale hydrodynamic model

© 2016, Allerton Press, Inc.The estimates of 137Cs emissions from the accident happened in Elektrostal at the beginning of April 12, 2013 are presented. The transport of radionuclides and their dry and wet deposition on the surface are computed using the Lagrangian stochastic model of the NOSTRADAMUS software package worked out by Nuclear Safety Institute of Russian Academy of Sciences. Prognostic fields of wind (horizontal and vertical components) in the lower troposphere, precipitation, and vertical and horizontal turbulence diffusivity coefficients in the lower atmosphere (up to 4 km) were used as input data. Prognostic fields were obtained using the WRF-ARW numerical mesoscale model

Comparison of the results of ⁸⁵Kr transport modeling with the ACURATE field experiment data

© 2017, Allerton Press, Inc.Currently the Nuclear Safety Institute of the Russian Academy of Sciences (NSI RAS) jointly with the Hydrometcenter of Russia is developing the system for forecasting the transfer of radio-active substances in the atmosphere in case of radiation accidents at Russian nuclear power plants. The operation of the system is based on the numerical hydrodynamic model which allows forecasting meteorological parameters and is coupled with the mesoscale dispersion model of the transfer ofradioactive substances in the atmosphere. The results are presented of 85Kr transport modeling under the conditions of the ACURATE experiment with three transport models: FLEXPART, HYSPLIT, and the model from the NOSTRADAMUS software package. It is demonstrated that all three Lagrangian models can give a qualitative description of concentration fields from the ACURATE experiment with the best value of the RANK metric (2.5) based on three statistics

APLIKASI MANAJEMEN KEGIATAN UNTUK ORGANISASI NON PROFIT BERBASIS WEBSITE

Suatu organisasi memiliki berbagai program kerja, yang di dalamnya ada kepanitian khusus. Biasanya manajemen kegiatan yang berisi pengelolaan keuangan pada masing-masing organisasi dan lembaga dikepalai oleh bendahara. Pengelolaan keuangan tersebut menjadi sebuah kebutuhan, karena bendahara tersebut wajib selalu melaporkan pencatatan keuangan. Tentu akan menjadi tidak efektif jika melakukan pencatatan keuangan harus melakukannya secara manual. Di samping susah, pencatatan secara manual sangat beresiko seperti rusak dan hilangnya buku pencatatan. Ada lagi pencatatan dengan cara lain yaitu menggunakan software yang sudah ada seperti Microsoft Excel, namun hal tersebut masih kurang efisien dan kurang efektif sehingga diperlukan tools pencatatan yang lebih baik agar mencapai tujuan dan sasaran yang diinginkan. Subjek penelitian yang dibahas pada penelitian ini adalah aplikasi pengelolaan keuangan untuk organisasi non profit berbasis website. Langkah pengembangan aplikasi yaitu menggunakan waterfall model. Dari penelitian yang dilakukan menghasilkan sebuah website tentang ”aplikasi manajemen kegiatan untuk organisasi non profit berbasis website” yang dapat digunakan untuk melakukan manajemen kegiatan bagi organisasi non profit sehingga pekerjaan seorang bendahara menjadi mudah dan efektif.Keywords: Manajemen Kegiatan, Nonprofit Online, Organisasi Non Profit

Metody zwiększenia odzysku metali nieżelaznych z niskiej jakości rudy miedziowo niklowej przed ługowaniem na hałdzie

The paper discusses two methods of ore pre-treatment. In the first case, ore crushing with sulfuric acid agglomeration was applied and followed heap leaching was applied. The second method involved electropulse destruction of pre-crushed ore, and then the heap leaching was performed.W pracy omówiono dwie metody wstępnej przeróbki rudy o niskiej zawartości miedzi i niklu. W pierwszym wariancie zastosowano przygotowanie rudy przy użyciu kwasu siarkowego i kolejno ługowanie na hałdzie. Drugi wariant polegał na obróbce wstępnie rozdrobnionej rudy w separatorze elektrycznym a następnie ługowanie na hałdzie

Origin of reef-style PGE mineralization in the Paleoproterozoic Monchegorsk Complex, Kola Region, Russia

The Paleoproterozoic Monchegorsk Complex in northwest Russia represents one of the largest layered intrusions in Europe and hosts several examples of broadly stratiform platinum group element (PGE) mineralization at different stratigraphic levels of the intrusion that have been suggested to represent reef-style mineralization. The Sopcha reef occurs in the ultramafic lower portion of the complex and constitutes an up to 6-m-thick succession of layered, mineralized dunite, harzburgite, and olivine-orthopyroxenite, with peak grades of 3.4 ppm Pt + Pd and 1.1 wt % Ni. Another PGE occurrence is hosted by the leucogabbronoritic to anorthositic Vuruchuaivench intrusion, which represents part of the mafic upper portion of the Monchegorsk Complex. The disseminated sulfide mineralization reaches up to 7.3 ppm Pt + Pd and is concentrated in several lenticular bodies over a strike length of ~5 km, rather than in a laterally continuous reef as previously suggested. Moreover, our work identified a previously unreported minor enrichment in precious metals of up to 0.2 ppm Pt + Pd in leucogabbroic rocks of the Monchetundra intrusion, which represents the uppermost portion of the Monchegorsk Complex and belongs to the more than 60-km-long mafic Main Ridge. Detailed lithophile and chalcophile element data, coupled with mineral chemistry, indicate that the PGE mineralization at Sopcha and Vuruchuaivench does not represent classic reef-style mineralization, which is commonly narrow and marked by a sharp increase in Cu/Pd ratios, reflecting the in situ sulfide saturation within a large magma chamber. Instead, it is more likely that the Sopcha reef was emplaced as a crustally contaminated and sulfide-saturated, olivine-rich crystal mush that was sourced from a deeper chamber. The Sopcha mineralization is characterized by Pd/Pt > 5 and Pd/Ir > 55, similar to contact-style mineralization elsewhere in the complex, possibly suggesting a common origin of the sulfides. The mineralized Vuruchuaivench rocks have similar Pd/Pt but much higher Pd/Ir ratios of up to 600, whereas the unmineralized host rocks, below as well as above the mineralization, have Pd/Ir ratios <100 and Pd/Pt ratios <2. These data indicate that the PGE-rich sulfides did not segregate in situ from the same magma that crystallized the host gabbronorites and anorthosites at Vuruchuaivench. Considering R factor and sulfide fractionation modeling results, we suggest that the mineralized Vuruchuaivench rocks represent a sill-like intrusion of gabbroic crystal mushes, which have entrained fractionated sulfide liquid that is related to an earlier sulfide saturation event. In contrast, the mineralized leucogabbroic rocks from the Monchetundra intrusion are characterized by a sharp increase in Cu/Pd ratios, which is consistent with a classic PGE reef model, in which sulfide saturation was triggered in situ by extensive fractionation and possibly affected the entire magma chamber. Furthermore, the Pd/Ir and Pd/Pt ratios of the mineralized horizon are distinctly lower at <66 and <1 in comparison to all other types of mineralization in the Monchegorsk Complex. The potential of this mineralization style elsewhere in the Main Ridge remains to be evaluated
