AbstractWe present a progress report on the dynamical analysis of the IRAS sample of OH/IR stars. This sample is complete within a distance of 8 kpc. We distinguish two groups of OH/IR stars, one with high and the other with low expansion velocity of the circumstellar shell.Using a quadratic programming method we fit a database of Galactic orbits to the observed distribution of radial velocities, longitudes and latitudes. The dynamical model yields a distribution function, based on two integrals of motion, for each group. Integration gives the density, the mean velocity and the velocity disper

AbstractThe phenomena of comet groups, i.e. sets of comets that exhibit similarity in their orbital elements, is investigated. A computer program based on the D-criterion of orbital similarity is used to search for comet pairs and groups. The reality of the groups is tested by making computer searches in random samples of comet orbits.The data base for the study is 599 long-period comet orbits. The degree of orbital similarity within a comet group was first assumed to be identical to that encountered in meteor streams. The computer search at this level produced five comet pairs plus two groups

Abstract:
Estimation of age is a crucial step for the identification of unknown individuals. Age is commonly assessed through macroscopic analytical methods based on the gross-examination of age degenerative changes in the skeleton. The choice of the methods relies on the taphonomic condition of the human remains and/or the skeletal element that is available. In cases of very fragmented bones, microscopic techniques remain one of the few approaches to estimate age. Thus, many histological age estimation methods have been developed for different bones and on different samples in the last forty years. Num

With these methods we can show that there exists other distinct 14 element, square, non-unique product sets in G that are not inversions or translations. Also, this paper answers the question as to whether every non-unique product set can have only 14 elements in the negative by pr

In this dissertation we present a novel computational method, as well as its software implementation, to compare two samples by a nonparametric likelihood-ratio test. The basis of the comparison is a mean-type hypothesis. The software is written in the R-language [4]. The two samples are assumed to be independent. Their distributions, which are assumed to be unknown, may be discrete or continuous. The samples may be uncensored, right-censored, left-censored, or doubly-censored. Two software programs are offered. The first program covers the case of a single mean-type hypothesis. The second pro

For the case of equal sample sizes we derive the exact null distribution by counting lattice paths confined to stay in the scaled alcove $\mathcal{A}_r$ of the affine Weyl group $A_{r-1}$.

An alternative is pooled testing (or ‘group testing’), where samples are mixed together in different pools, and those pooled samples are tested. When the prevalence of the disease is low and the accuracy of the test is fairly high, pooled testing strategies can be more efficient than individual testing.

Genetic risk’s values of ischemic stroke were determined in the groups of patients and control, and its distribution between 6 groups of SNP combinations was analyzed in accordance with the suggested model. The differences by genetic risk values between the patient’s samples and the control group were determined as statistically significant (p<0.01) for two groups of loci associated with an increased risk of atherothrombotic and cardioembo

ABSTRACT Introduction: Shoulder impingement syndrome is the most common diagnosis of shoulder dysfunction. Physical therapy has been found to be effective in reducing pain and disability in these patients. Methodology: The purpose of this study was to compare the effectiveness of two physical therapy interventions in the treatment of primary shoulder impingement syndrome: 1) supervised exercise only, and 2) supervised exercise with manual therapy techniques. Thirty-six subjects diagnosed with primary shoulder impingement were randomly assigned to one of these two groups. Physiotherapy protocol

The research was carried out in the field at the Central experimental base of the Federal Williams Research Center. The object of research was 13 samples of timothy-grass. Samples were sown according to the scheme of a standard collection nursery. All studies and observations were carried out on the herbage of the 2nd and 3rd year of life. Statistical processing of the research results indicates a low level of variation. The sample № 414 stood out high content of raw protein and raw fat.

Abstract:
This study aims to determine whether public speaking anxiety can be reduced when the oral presentation is performed in an online environment. For the purpose of the research, two groups of approximately equal numbers of university students delivered oral presentations: the control group in the classroom and the experimental group online using the MS Teams platform. Their levels of self-perceived communication anxiety and fear of negative evaluation were subsequently assessed using the Oral Presentation Anxiety Scale, which was designed specifically for this study. The results show that the onl

Abstract:
Monitoring ecosystems is vital to understanding trends over time and key to detecting change so that managers can address perturbations. Freshwater streams are the lifeblood of the surrounding landscape, and their health is a measure of the overall watershed integrity. Streams are the culmination of upland processes and inputs. Degradation on the landscape as well as changes to the stream itself can be detected using biota living in these ecosystems. Aquatic invertebrates are excellent indicators of ecosystem quality because they are relatively long-lived, sessile, diverse, abundant and their

A sample of PAES participants was surveyed in 2002, from which a sub-sample was re-surveyed in 2005 along with a control group of non-participating households. The methodology included two adoption models (Conservation Practices and Conservation Structures) using two separate samples (PAES beneficiaries 2002-2005 and beneficiaries-control group 2005), and two probit models were estimated to examine the disadoption of practices and st

Abstract:
Although concrete is the most widely used building material in the world, its limited tensile strength makes cracking a common phenomenon in concrete elements. This study investigates the potential of autonomous self-healing as an eco-friendly and lowcost method to increase the durability of concrete. The crack-healing potential of different types of high-alkaline-tolerant bacteria or calcite-precipitation microorganisms is investigated. High-alkaline-tolerant bacteria and calcite-precipitation microorganisms were used to retrofit lab-fractured concrete samples. The samples healed with each of
