Abstract. Background: The hematopoietic system is classified as the most radiosensitive body system. Research of occupational radiation-induced hematological shifts continues to be a relevant question of occupational radiation safety. Aim: Analysis of leukocytal indices dynamics depending on the accumulated dose of occupational external gamma-exposure. Methods: The database «Leukemia in the cohort of Mayak Production Association workers hired in 1948-1958» was used as the material. Leukocytal indices were estimated based on 19592 peripheral blood analyses; dynamics of hematological shifts was traced according to accumulation of absorbed doses of occupational external gamma-radiation; comparative analysis of hemogramms with a group of workers without oncohematological pathology was carried out. Nonparametric statistical methods were applied. Results: The period of dose accumulation at the same total dose of occupational external gamma-exposure was much different in the study groups, it was much shorter for individuals who later died of leukemia. Leukocytal indices in groups were most different in the range of accumulated absorbed doses of external gamma exposure equal to 2 – 2.5 Gy and had the largest amplitude of values among the workers diagnosed for leukemia later. Conclusion: The estimation of leukocytal indices may be used as the tool for early detection of adverse hematological shifts in cell lines and may be the indicator of pathologic hemapoiesis in the exposed workers before clinical manifestation of hematological pathology.

The objective of the study was to identify the marketing structure and opportunities of almond products in the Samangan and Balkh provinces. The primary data were obtained from questionnaires conducted by face to face interviews with the 125 small scale almond producers and 42 intermediaries, and the secondary data collected from various sources. The collected data were analyzed using parametric and nonparametric statistical methods. According to the results of the study, the average age was 45.13 years for almond farmers and 41.44 years for intermediaries. The average schooling years were 5.40 years for farmers and 9.43 years for intermediaries. While most of the farmers were elementary school graduates, the majority of the intermediaries were secondary school graduates. The strongest aspects of the almond marketing sector in the region are the experience of the farmers and their high interest in this product. The most important opportunities are the good experience of farmers, the adaptation of almonds in Balkh and Samangan, the interest of the farmer in horticulture, availability of substantial varieties of almonds, exports competitiveness of almond products of the region, and the favorable climatic conditions. The study concludes that the government and NGOs should support producers and intermediaries in developing the infrastructure of local markets. They should provide farmers with agricultural inputs at affordable prices, implement capacity building programs, inform all stakeholders on input and product prices, develop credit opportunities, and support farmers' organizations.

Belimbing wuluh (Averrhoa bilimbi L.) is a well-known traditional medicinal plant that thrives in Indonesia. The amount of fruit production per year can reach 1500 pieces per plant but is easily damaged, its shelf life is short, the taste of sour fruit causes not many people to consume the fruit fresh, in addition, have a low selling price and economic value. Therefore to increase the storage capacity, selling price, and economic value it is necessary to process into functional foods such as jelly drinks. This study aims to determine consumer acceptance of Belimbing wuluh (Averrhoa bilimbi L.) jelly drink products. The method of this research was the design of random group. The first factor is the concentrate of carrageenans (1%; 1,5%; 2%) and the second factor is the concentrate of sugars (13%, 15%). Observations on Belimbing wuluh (Averrhoa bilimbi L.) jelly drink (taste, color, aroma, suction power, and mouthfeel) by 25 untrained panelists. Organoleptic test data were analyzed by nonparametric statistical methods using the Friedman test. The results showed that the best treatments on consumer acceptance of jelly drink Belimbing wuluh (Averrhoa bilimbi L.) in an organoleptic manner was obtained from treatment with 1,5% carrageenan and 15% sugar with a product value of 2,39 with a mean value of panelist favorability to taste on 6,23; the color on 7,76; aroma on 7,19; suction power on 8,5; mouthfeel on 7,54.

This paper analyses the public procurement auctions for snow removal contracts to find out whether bid-rigging occurred. Due to the limited participation in the auction processes, detection of anticompetitive agreements was possible. The econometric analysis used in our study supported the findings of a cartel agreement. Cluster analysis, statistical hypothesis, normality and symmetry and nonparametric tests reveal two types of auctions: competitive and noncompetitive bids. The aim of this paper is to analyze the public procurement auctions with nonparametric statistical methods. Our findings are in line with the literature in the field.

Abstract The currently active, prospective multi-center Head Start 4 (HS4) trial for CNS embryonal tumors differs from prior HS I-III trials by utilizing absolute phagocyte count (APC) as a measure of myeloid recovery instead of absolute neutrophil count. The aim of this study was to determine if utilization of APC resulted in unanticipated treatment-related toxicities during induction chemotherapy for patients enrolled on HS4. Review of the RedCap database was conducted for treatment-related CTCAE grade 3 and 4 toxicities. Data were summarized descriptively. Nonparametric statistical methods were used for comparisons. At the time of this most recent analysis, a total of 180 induction cycles were completed for the 57 patients enrolled. Of the 57 patients, nine voluntarily discontinued therapy after completing a median of three cycles each. These patients had a higher number of documented infections (59% versus 24%, p=0.0004). Veno-occlusive disease (VOD) occurred in five patients, three of whom voluntarily discontinued therapy. Since the protocol amendment utilizing milligram per kilogram dosing for patients less than six years of age, there have been no documented episodes of VOD. The overall toxicities for this cohort were comparable to those reported for induction chemotherapy in HS I-II trials. The toxic death rate is lower for HS4 compared to HS I-II (0.018% versus 4.7–6%) (Chi et al 2004). Other than the high rate of infection, possibly associated with shorter duration of the immediately prior cycles, the use of APC as part of a dose-compression strategy in HS4 does not appear associated with more significant toxicities.

The possibility of applying the nonparametric statistical methods to solve the tasks of investigating and appraising the index status of nutrition of military servicemen is considered. The experience to use in parallel several statistical algorithms for testing hypotheses is shown. An approach was worked out to test a sequence of hypotheses going one after another when testing the previous hypothesis influences the choice of subsequent hypothesis to test. This approach is formalized as a scheme to incrementally estimate the status of nutrition of military servicemen. The proposed model of status of nutrition exploration is used to obtain the quality and quantity digital estimation of the expected trend of a certain controllable parameter or a group of parameters of status of nutrition. It is established that among the considered indicators of the status of nutrition, the prevailing number of them has undergone a regular change in different periods of a prolonged sea voyage, depending on the balance of the main food components (proteins, fats and carbohydrates) with other nutrients and on the energy costs of the body of servicemen. The algorithm for studying the status of nutrition of servicemen with the use of nonparametric methods of statistical analysis made it possible to reveal a number of changes in metabolic processes occurring at the prenosological level and conditioned by the peculiarities of nutrition and the nature of military professional activity. On the basis of the research results obtained, requirements for the content of vitamins and minerals in the diet, as well as vitamin-mineral complexes, necessary for strengthening the body’s protective functions and preventing various diseases, can be formulated. Applying this model enlarges greatly the exploration possibilities when the methodical recommendations and normative documents to regulate the nutrition of military servicemen are developed.
