description: Here we present eight new candidates for exoplanets detected by the transit method at the Special Astrophysical Observatory of the Russian Academy of Sciences. Photometric observations were performed with a 50-cm robotic telescope during the second half of 2020. We detected transits with depths of $Δm = 0.056-0.173^m$ and periods $P = 18.8^h-8.3^d$ in the light curves of stars with magnitudes of $m = 14.3-18.8^m$. All considered stars are classified as dwarfs with radii of $R_* = 0.4-0.6 R_{sun}$ (with the uncertainty for one star up to $1.1 R_{sun}$). We estimated the candidate radii (all are greater than 1.4 times the Jovian radius), semi-major axes of their orbits ($0.012-0.035 AU$), and other orbital parameters by modelling. We report the light curves with transits for two stars obtained in 2022 based on individual observations.

description: We formalize the derivation of a generalized coarse-graining $n$-resolved master equation by introducing a virtual detector counting the number of transferred charges in single-electron transport. Our approach enables the convenient inclusion of coherences and Lamb shift in counting statistics. As a Markovian example with Lindblad-type density matrices, we consider the Born-Markov-Secular (BMS) approximation which is a special case of the non-Markovian dynamical coarse graining (DCG) approach. For illustration we consider transport through two interacting levels that are either serially or parallelly coupled to two leads held at different chemical potentials. It is shown that the coherences can strongly influence the (frequency-dependent) transport cumulants: In the serial case the neglect of coherences would lead to unphysical currents through disconnected conductors. Interference effects in the parallel setup can cause strong current suppression with giant Fano factors and telegraph-like distribution functions of transferred electrons, which is not found without coherences. We demonstrate that with finite coarse graining times coherences are automatically included and, consequently, the shortcomings of the BMS approximation are resolved.

title: A Comparative Study of Boron Adsorption By a Calcareous and an Acid Soil
Creators: name: Ali Rashid, Namik M.
Publisher: name: Utah State University
Year: 1971

description: The adsorption of boron by Aiken clay loam and Vernal sandy loam was studied in the boron equilibrium concentration range of 0 to 40 ppm. Adsorption data were obtained at 11, 20 and 30°C. The data were analyzed by the application of the Langmuir adsorption isotherm. It was concluded that, in both Soils, the adsorption of boron occurred on three distinct sites or regions.
The acid ferrigenous Aiken soil had a higher adsorption capacity for boron than the calcareous Vernal soil when compared on a unit mass basis. On the unit area basis, however, the Vernal soil adsorbed more boron than the Aiken soil. The isoteric heat of adsorption showed that boron reacted more energetically with the Vernal soil. The calculated 6H values were -7.6 K cal/M and -3.3 K cal/M for Vernal and Aiken soils, respectively.
The capacity of both soils to adsorb phosphorus was higher than their capacity to adsorb boron. The presence of adsorbed phosphate did not greatly reduce the amount of boron adsorbed by either soil studied. In the Vernal soil, phosphate was three times more efficient in replacing boron than in the Aiken soil. Also, chloride was found to desorb more boron from the Aiken soil than phosphate. However, neither phosphate nor chloride was found to be effective in reducing to any great extent the adsorption of boron by the two soils studied.

description: Aims. The treatment of astronomical image time series has won increasing attention in recent years. Indeed, numerous surveys following up on transient objects are in progress or under construction, such as the Vera Rubin Observatory Legacy Survey for Space and Time (LSST), which is poised to produce huge amounts of these time series. The associated scientific topics are extensive, ranging from the study of objects in our galaxy to the observation of the most distant supernovae for measuring the expansion of the universe. With such a large amount of data available, the need for robust automatic tools to detect and classify celestial objects is growing steadily. Methods. This study is based on the assumption that astronomical images contain more information than light curves. In this paper, we propose a novel approach based on deep learning for classifying different types of space objects directly using images. We named our approach ConvEntion, which stands for CONVolutional attENTION. It is based on convolutions and transformers, which are new approaches for the treatment of astronomical image time series. Our solution integrates spatio-temporal features and can be applied to various types of image datasets with any number of bands. Results. In this work, we solved various problems the datasets tend to suffer from and we present new results for classifications using astronomical image time series with an increase in accuracy of 13%, compared to state-of-the-art approaches that use image time series, and a 12% increase, compared to approaches that use light curves.
title: Leadership in Sports
Creators: name: Bliss, Gary H.
Publisher: name: Utah State University
Year: 1965

description: Players with leadership ability are persons coaches are constantly striving to find, develop and use in their sports program. Although coaches are groping for the people that possess these qualities, the identification of the qualities of leadership is a very difficult and evasive task. The major problem the coach faces is not having a lack of leadership on his team, but one of identifying the qualities of leadership and then using the person or persons with these recognized characteristics to the advantage of the team and its common goals.
Nelson (31) emphasizes that coaches and physical educators have greatest knowledge and work most closely with the purely physical, mechanical aspect of sports, as might be expected; but too often this results in a tendency to assume that success in sports, the finished product, is almost a pure function of a single process--the physical process. We readily recognize that maximum performance in the final analysis is not a simple thing. It is structured from many facets of the individual--his intelligence, various personality traits, spiritual and social background, etc., as well as his physical endowments.
Very little is known about player attitudes and the psychological or emotional aspects which affect success in athletic competition. This aspect of performance is not only important but relatively unexplored.
A coach often observes leadership in sports competition and has witnessed the effect that good leadership has on team performance. Observation of this leadership ability and its influence on the team is usually the result of the experience in associating with the players. Coaches seldom have the skills and knowledge necessary to define, objectively measure, and determine what psychological variables give a person these leadership qualities.
Eisenhower (11) states that leaders are waiting in the wings, waiting to be called and used when the situation needing leadership presents itself. He believes that any man who does his work well, who is justifiably self- confident, and not unduly disturbed by jeers of the cynics and the shirkers, any man who stays true to decent motives and is considerate of others is, in essence, a leader.
Leadership is a very evasive quality to measure, but through testing and evaluating an athlete's personality, a coach may gain objective insight to enable him to adopt more successful coaching techniques in using the qualities of leadership and to form a basis on which to predict future athletic success.

description: This is a survey of recent results on quantum ergodicity, specifically on the large energy limits of matrix elements relative to eigenfunctions of the Laplacian. It is mainly devoted to QUE (quantum unique ergodicity) results, i.e. results on the possible existence of a sparse subsequence of eigenfunctions with anomalous concentration. We cover the lower bounds on entropies of quantum limit measures due to Anantharaman, Nonnenmacher, and Rivière on compact Riemannian manifolds with Anosov flow. These lower bounds give new constraints on the possible quantum limits. We also cover the non-QUE result of Hassell in the case of the Bunimovich stadium. We include some discussion of Hecke eigenfunctions and recent results of Soundararajan completing Lindenstrauss' QUE result, in the context of matrix elements for Fourier integral operators. Finally, in answer to the potential question `why study matrix elements' it presents an application of the author to the geometry of nodal sets.

description: Fertilizer, feed and machinery dealers we re interviewed to obtain the extent of the services which they provided to farmers in Cache County. One machinery dealer provided a service in the form of a rental program while all others provided none. Fertilizer dealers provided spreaders while feed dealers provided only a delivery service.
The Farm Service Division of the Amalgamated Sugar Company was examined as a case study. Budgets for different sizes of beet growers were formulated and compared to evaluate the services provided. It was determined that the farmers in the 0-10 acre category received a net return per acre of $107.36 while the farmers in the over 40 acre category who did not use the service received a net return per acre of $105.00. It was deduced that the Farm Service Division was a benefit to the smaller farmers.
Problems which the farmers encountered with the services were discussed, and a theoretical model of the services was presented. Recommendations were given for improvements in the services.

We quantify how well we might be able to distinguish between these scenarios with a deep spectroscopic survey using the future Nancy Grace Roman Space Telescope. Since Roman will be able to carry out blind spectroscopic surveys of Ly$α$ emitters continuously between $7 3-4σ$ at several redshifts between $75-8σ$) across the epoch of reionization, and would yield a detailed history of the reionization of the IGM and its effect on Lyman-$α$ Emitter clustering.

title: A Survey of the State of Utah for Areas Infested with the Stem Nematode of Alfalfa
Creators: name: Buxton, Dwayne R.
Publisher: name: Utah State University
Year: 1965

description: Plant nematodes belong to a large group of invertebrates known as round worms, They derive their name from the Greek word "nema," meaning thread. In literature some authors refer to nematodes as nemas. In England and many parts of the United States, plant-parasitic nematodes are called eelworms.
While some damage to plants results from mechanical injury, salivary secretions injected by the nematode into the plant are usually the major cause of damage. Experiments conducted in the first part of the present century have demonstrated large differences in plant growth in soil infested with nematodes and soil freed of nematodes by chemicals. Any plant subjected to nematode attack is reduced in growth.
The most important nematode which attacks and retards the growth of alfalfa in Utah is the stem nematode. This parasite has been reported in most of the major alfalfa-producing counties of the state. In certain areas the nematode is prevalent to such a degree that only resistant varieties can be grown if the crop is to remain for more than two or three years. In other areas stands and yields are reduced in varying degrees. In many additional areas it is not known if the stem nematode is present, since a complete survey of the state has never been made.
The objectives of this investigation were to determine the distribution of the stem nematode of alfalfa through a complete survey of the state. The physical factors of the plant and soil which may be correlated with the presence of the nematode were likewise surveyed.

description: There is a common belief in the trucking industry that, while most truck and bus drivers are both conscientious and safe, a relatively small percentage of commercial motor vehicle (CMV) drivers are associated with a significant and inordinate percentage of the overall number of motor carrier crashes. These drivers are considered to be "high risk" drivers, and the study summarized in this Tech Brief focuses on these commercial drivers. This project explores factors associated with "high risk drivers" and the means by which carriers can reduce crash risk through various safety management practices and other safety interventions.

description: We investigate the spatial extent and structure of the Pegasus dwarf irregular galaxy using deep, wide-field, multicolour CCD photometry from the Sloan Digital Sky Survey (SDSS) and new deep HI observations. We study an area of ~0.6 square degrees centred on the Pegasus dwarf that was imaged by SDSS. Using effective filtering in colour-magnitude space we reduce the contamination by foreground Galactic field stars and increase significantly the contrast in the outer regions of the Pegasus dwarf. Our extended surface photometry, reaches down to a surface brightness magnitude mu_r~32 mag/sq.arcsec. It reveals a stellar body with a diameter of ~8 kpc that follows a Sersic surface brightness distribution law, which is composed of a significantly older stellar population than that observed in the ~2 kpc main body. The galaxy is at least five times more extended than listed in NED. The faint extensions of the galaxy are not equally distributed around its circumference; the north-west end is more jagged than the south-east end. We also identified a number of stellar concentrations, possibly stellar associations, arranged in a ring around the main luminous body. New HI observations were collected at the Arecibo Observatory as part of the ALFALFA survey. They reveal an HI distribution somewhat elongated in RA and about 0.3 deg. wide, with the region of highest column density coincident with the luminous galaxy. The HI rotation curve shows a solid-body rotation behaviour, with opposite ends differing by 15 km/s. There is a stream to lower velocities about 5 arcmin from the centre of the galaxy. We were able to measure ugriz colours in a number of apertures using the SDSS data and compared these with predictions of evolutionary synthesis models. (abridged)

description: We investigate the nontrivial characteristics of modulational instability (MI) in a system of Bragg gratings with saturable nonlinearity. We also introduce an equal amount of gain and loss into the existing system which gives rise to an additional degree of freedom, thanks to the concept of $\cal PT$- symmetry. We obtain the nonlinear dispersion relation of the saturable model and discover that such dispersion relations for both the conventional and $\cal PT$- symmetric cases contradict with the conventional Kerr and saturable systems by not displaying the typical signature of loop formation in either the upper branch or lower branch of the curve drawn against the wavenumber and detuning parameter. We then employ a standard linear stability analysis in order to study the MI dynamics of the continuous waves perturbed by an infinitesimal perturbation. The main objective of this paper is twofold. We first investigate the dynamics of the MI gain spectrum at the top and bottom of the photonic bandgap followed by a comprehensive analysis carried out in the anomalous and normal dispersion regimes. As a result, this perturbed system driven by the saturable nonlinearity and gain/loss yields a variety of instability spectra, which include the conventional side bands, monotonically increasing gain, the emergence of a single spectrum in either of the Stokes wavenumber region, and so on. In particular, we observe a remarkably peculiar spectrum, which is caused predominantly by the system parameter though the perturbation wavenumber boosts the former. We also address the impact of all the physical parameters considered in the proposed model which include coupling coefficient, dispersion parameter, and saturable nonlinearity on the phenomenon of MI for different $\cal PT$- symmetric regimes ranging from unbroken to broken one in greater detail.

description: We solve the entanglement classification under stochastic local operations and classical communication (SLOCC) for all multipartite symmetric states in the general $N$-qubit case. For this purpose, we introduce 2 parameters playing a crucial role, namely the \emph{diversity degree} and the \emph{degeneracy configuration} of a symmetric state. Those parameters give rise to a simple method of identifying operational families of SLOCC entanglement classes of all symmetric $N$-qubit states, where the number of families grows as the partition function of the number of qubits.

description: We consider coherent dynamics of graphene charged carriers exposed to an intense few-cycle linearly polarized laser pulse. The results, obtained by solving the generalized semiconductor Bloch equations numerically in the Hartree-Fock approximation, taking into account many-body Coulomb interaction, demonstrate strong dependence of the valley polarization on the carrier-envelope phase (CEP), which is interpolated by the simple sinusoidal law. Then we consider harmonic generation in multi-cycle laser field by graphene preliminary exposed to an intense few-cycle laser pulse. We show that the second harmonic's intensity is a robust observable quantity that provides a gauge of CEP for pulse durations up to two optical cycles, corresponding to 40 $\mathrm{fs}$ at the wavelength of 6.2 $\mathrm{μm}$.

title: Estimation of Optimum Size, Shape, and Replicate Number of Safflower Plots for Yield Trials
Creators: name: Polson, David Ernest
Publisher: name: Utah State University
Year: 1964

description: The success of a breeding program depends upon the ability of the plant breeder to not only develop new lines, but also to determine which lines or varieties are superior. For this purpose, yield trials are an important yardstick for determining the value of the trial in assessing the merits of the different lines.
Variation encountered is due to several factors; with true genetic differences, environment, and human error being of major importance. In order for yield trials to give meaningful information on a line or variety, it is essential that variation due to human error and environment be reduced to a minimum. Uniform space planting, careful cultivation, and irrigation can help reduce the human error. However, the effect of environment, mainly soil heterogeneity, is not so easily handled.
Randomization, replication, and planting experimental plots of the proper shape with sufficient size to give the desired information are techniques devised to minimize the effect of soil heterogeneity. In general, it has been found that the larger the experimental plots, the smaller the variation (1, 23). Also, plots with a large length to width ratio lying in the direction of greatest soil variability have been found to decrease the variability of the yield trial (2, 8, 32, 35). However, both expense and convenience will modify the size and shape of plot that is desired. The optimum size and shape of a plot would be one that gives a maximum amount of information at a minimum cost and be of convenient handling dimensions. Such information must be determined for each individual crop.

description: A matching $M$ in a graph $G$ is {\em semistrong} if every edge of $M$ has an endvertex of degree one in the subgraph induced by the vertices of $M$. A {\em semistrong edge-coloring} of a graph $G$ is a proper edge-coloring in which every color class induces a semistrong matching. In this paper, we continue investigation of properties of semistrong edge-colorings initiated by Gyárfás and Hubenko ({Semistrong edge coloring of graphs}. \newblock {\em J. Graph Theory}, 49 (2005), 39--47). We establish tight upper bounds for general graphs and for graphs with maximum degree $3$. We also present bounds about semistrong edge-coloring which follow from results regarding other, at first sight non-related, problems. We conclude the paper with several open problems.

description: Sun-as-a-star coronal plasma composition, derived from full-Sun spectra, and the F10.7 radio flux (2.8 GHz) have been shown to be highly correlated (r = 0.88) during solar cycle 24. However, this correlation becomes nonlinear during increased solar magnetic activity. Here, we use co-temporal, high spatial resolution, multi-wavelength images of the Sun to investigate the underlying causes of the non-linearity between coronal composition (FIP bias) and F10.7 solar index correlation. Using the Karl G. Jansky Very Large Array (JVLA), Hinode/EIS (EUV Imaging Spectrometer), and the Solar Dynamic Observatory (SDO), we observed a small active region, AR 12759, throughout the solar atmosphere from the photosphere to the corona. Results of this study show that the magnetic field strength (flux density) in active regions plays an important role in the variability of coronal abundances, and it is likely the main contributing factor to this non-linearity during increased solar activity. Coronal abundances above cool sunspots are lower than in dispersed magnetic plage regions. Strong magnetic concentrations are associated with stronger F10.7 cm gyroresonance emission. Considering that as the solar cycle moves from minimum to maximum, the size of sunspots and their field strength increase with gyroresonance component, the distinctly different tendencies of radio emission and coronal abundances in the vicinity of sunspots is the likely cause of saturation of Sun-as-a-star coronal abundances during solar maximum, while the F10.7 index remains well correlated with the sunspot number and other magnetic field proxies.

title: The Role of Cooperative Societies in the Economic Development of India
Creators: name: Rananavare, A. M.
Publisher: name: Utah State University
Year: 1964

description: The idea of cooperation is not new to man. It is as old as man himself. Cooperatives are an almost universal form of organization today found in practically all countries and used by people in many ways. The cooperatives are formed to secure low cost credit, to purchase supplies and equipment for farming and household needs, to market products, even to secure many services, like electric power, irrigation, health, and insurance. Cooperatives can be used in many ways to benefit people in the everyday needs of life.
The meaning of cooperation is that isolated and powerless individuals can, by combining with one another, achieve advantages available to the rich and the powerful so that they may advance not only materially but also morally. In other words a cooperative is a business organization that is owned by those who use its services, the control of which rests equally with all the members. It is voluntary and democratic and the moral element is as important as the material one. Furthermore, it recognizes social, educational, and community values.
It is easier to understand the concept of the cooperative by knowing its specific objectives. They can be summed as follows:
1) They aim to provide goods and services.
2) They aim to eliminate the unnecessary profits of middlemen in trade and commerce.
3) They seek to prevent the exploitation of the weaker members of society.
4) They aim to protect the rights of people both as producers and consumers.
5) They promote mutual understanding and education among their members and people in general.
Mr. W. P. Watkins of International Cooperative Alliance defines cooperation as: "A system of social organization based on the principles of unity, economy, democracy, equity, and liberty." 1

description: We study the leading electroweak corrections in the precision measurement of the strange form factors. Specifically, we calculate the two-boson-exchange (TBE), two-photon-exchange (TPE) plus $γZ$-exchange ($γZ$E), corrections with $Δ(1232)$ excitation to the parity-violating asymmetry of the elastic electron-proton scattering. The interplay between nucleon and $Δ$ contributions is found to depend strongly on the kinematics, as $δ_Δ$ begins as negligible at backward angles but becomes very large and negative and dominant at forward angles, while $δ_N$ always stays positive and decreases monotonically with increasing $ε$. The total TBE corrections to the extracted values of $G^{s}_{E}+βG^{s}_{M}$ in recent experiments of HAPPEX and G0 are, depending on kinematics, found to be large and range between 13% to -75% but small in the case of A4 experiments.

description: Context: Solar flares are the result of the sudden release of magnetic energy in the corona. Much of this energy goes into accelerating charged particles to high velocity. These particles travel along the magnetic field and the energy is dissipated when the density gets high enough, primarily in the solar chromosphere. Modelling this region is difficult because the radiation energy balance is dominated by strong, optically thick spectral lines. Aims: Our aim is to provide the community with realistic simulations of a flaring loop with an emphasis on the detailed treatment of the chromospheric energy balance. This will enable a detailed comparison of existing and upcoming observations with synthetic observables from the simulations, thereby elucidating the complex interactions in a flaring chromosphere. Methods: We used the 1D radiation hydrodynamics code RADYN to perform simulations of the effect of a beam of electrons injected at the apex of a solar coronal loop. A grid of models was produced, varying the total energy input, the steepness, and low-energy cutoff of the beam energy spectrum. Results: The full simulation results for a grid of models are made available online. Some general properties of the simulations are discussed.

description: Electronic Product Code (EPC) is the basis of a pervasive infrastructure for the automatic identification of objects on supply chain applications (e.g., pharmaceutical or military applications). This infrastructure relies on the use of the (1) Radio Frequency Identification (RFID) technology to tag objects in motion and (2) distributed services providing information about objects via the Internet. A lookup service, called the Object Name Service (ONS) and based on the use of the Domain Name System (DNS), can be publicly accessed by EPC applications looking for information associated with tagged objects. Privacy issues may affect corporate infrastructures based on EPC technologies if their lookup service is not properly protected. A possible solution to mitigate these issues is the use of online anonymity. We present an evaluation experiment that compares the of use of Tor (The second generation Onion Router) on a global ONS/DNS setup, with respect to benefits, limitations, and latency.

title: Weber Basin Water Conservancy District: An Economic Appraisal
Creators: name: Pendse, Dilipsinha C.
Publisher: name: Utah State University
Year: 1967

description: Information on Water Conservancy Districts in Utah was collected by mail and personal visits to district offices. There are a total of 12 districts in Utah, but only five were selling water in 1965. The water development projects of the remaining seven were not finished. Some of the districts are small and consolidation would bring them many advantages of large scale operation.
The success of the Weber Basin Water Conservancy District was evaluated from the point of view of economic efficiency . Insistence on long term contract, adherence to water duty requirements set by the Bureau of Reclamation, inability to sell water on land acreages larger than 160 acres, pricing based on costs of producing and distributing water, and disallowing resale or transfer of water rights were hindrances to the efficient allocation of water.
High projections of demand, high prices, and salt content in the water were impediments to the District in sel ling all water available.
Renormalization approach to the analysis and design of Hermitian and non-Hermitian interfaces

description: I describe a concrete and efficient real-space renormalization approach that provides a unifying perspective on interface states in a wide class of Hermitian and non-Hermitian models, irrespective of whether they obey a traditional bulk-boundary principle or not. The emerging interface physics are governed by a flow of microscopic interface parameters, and the properties of interface states become linked to the fixed-point topology of this flow. In particular, the quantization condition of interface states converts identically into the question of the convergence to unstable fixed points. As its key merit, the approach can be directly applied to concrete models and utilized to design interfaces that induce states with desired properties, such as states with a predetermined and possibly symmetry-breaking energy. I develop the approach in general, and then demonstrate these features in various settings, including for the design of circular, triangular and square-shaped complex dispersion bands and associated arcs at the edge of a two-dimensional system. Furthermore, I describe how this approach transfers to nonlinear settings, and demonstrate the efficiency, practicability and consistency of this extension for a paradigmatic model of topological mode selection by distributed saturable gain and loss.

description: We consider the critical behavior of the random q-state Potts model in the large-q limit with different types of disorder leading to either the nonfrustrated random ferromagnet regime or the frustrated spin glass regime. The model is studied on the diamond hierarchical lattice for which the Migdal-Kadanoff real-space renormalization is exact. It is shown to have a ferromagnetic and a paramagnetic phase and the phase transition is controlled by four different fixed points. The state of the system is characterized by the distribution of the interface free energy P(I) which is shown to satisfy different integral equations at the fixed points. By numerical integration we have obtained the corresponding stable laws of nonlinear combination of random numbers and obtained numerically exact values for the critical exponents.

description: Biological active matter is typically tightly coupled to chemical reaction networks affecting its assembly-disassembly dynamics and stress generation. We show that localized states can emerge spontaneously if assembly of active matter is regulated by chemical species that are advected with flows resulting from gradients in the active stress. The mechanochemical localized patterns form via a subcritical bifurcation and for parameter values for which patterns do not exist in absence of the advective coupling. Our work identifies a generic mechanism underlying localized cellular patterns.

description: Eesmärgid. Anda ülevaade suitsetamisest loobumise nõustamisest (SLN) Tartu Ülikooli Kliinikumi (TUK) kopsukliiniku SLN-kabinetis aastatel 2006–2010. Eesmärgiks oli kirjeldada loobumisprotsessis püsimist ja analüüsida selle seost loobumisega seotud teguritega. Metoodika. Uuringusse võeti kõik 566 inimest, kes olid uuringuperioodil SLN-kabinetti pöördunud. Loobumisega seotud teguritena käsitleti sugu, vanust, motivatsiooni, pakkaastaid, depressiooni ja ärevushäirete esinemist, nikotiinisõltuvuse tugevust ning määratud ravi. Kirjeldavas analüüsis kasutati sagedustabeleid ja kirjeldavaid statistikuid, rühmadevahelist erinevust analüüsiti X2-testi ja Manni-Whitney U-testiga. Toenäosust püsida suitsuvaba hinnati Kaplani-Meieri meetodiga. Loobumise seoseid erinevate teguritega hinnati Coxi regressioonimudeli abil. Arvutati valja riskide suhted (HR) koos 95% usaldusvahemikuga (95% uv).Tulemused. Suitsetamisest loobumist alustas 54,6% pöördunutest. Kõige rohkem hakkasid loobujad taas suitsetama kahe nadala jooksul pärast esimest suitsuvaba päeva. Loobumismäär kabinetti pöördunute hulgas 12kuulise perioodi lopus oli 9,7%. Loobumist alustanute tinglik tõenaosus püsida vähemalt 12 kuud suitsuvabana oli 22,2%. Mõnevõrra suurema tõenäosusega hakkasid loobumisperioodi jooksul taas suitsetama loobujad, kes olid alla 25aastased, kellel oli depressioon ja kellele määrati nikotiinasendusravi (ravimi kasutamine teadmata).Järeldused. Loobumismäära järgi võib aastatel 2006–2010 suitsetamisest loobumise nõustamist TÜK kopsukliinikus pidada tõhusaks, kuid parandada tuleb pöördujate kaasamist loobumisprotsessi. Suitsuvabana püsimise edukuse suurendamiseks tuleb tähelepanu pöörata indiviidipõhistele loobumisega seotud teguritele.

title: A Suggested Mathematics Curriculum for Preparation of Teachers of Modern Secondary School Mathematics in Utah
Creators: name: Philips, Harold Nolan
Publisher: name: Utah State University
Year: 1967

description: "New math" has drastically changed secondary mathematics and the demands on the secondary ma thematics teacher. The changes and effects of changes w re studied with emphasis on suggested programs in teacher preparation.
Questionnaires were given to one hundred four secondary mathematics teachers in Utah. Fifty-eight were returned, of which fifty were usable. The questionnaire contained twenty-six mathematics courses offered to mathematics education majors in Utah universities. The teachers indicated which courses were valuable to them in teaching secondary school mathematics. Rank order correlation coefficients were calculated among subgroups of the questionnaire to determine internal consistency. All coefficients were above the 1 per cent significance level. The first fifteen courses listed in rank order according to the percentage of teachers who felt each course was valuable are: college algebra, trigonometry, analytic geometry, differential calculus, modern algebra, methods for secondary mathematics teachers , mathematics for secondary school teachers, foundations of mathematics, integral calculus, number theory, history of mathematics, foundations of geometry, solid geometry, logic, and foundations of algebra.
On the basis of the courses generally recommended for prospective modern mathematics teachers by nationally interested groups and the results of the evaluations of courses by Utah mathematics teachers, the following program in mathematics was proposed for prospective mathematics teachers in Utah.
Mathematics education majors should take:
College Algebra (or equivalent) Trigonometry (or equivalent) Analytic Geometry Differential Calculus Abstract Algebra (at least one course ) College Geometry (at least one course other than Analytic Geometry) Mathematics for Secondary School Teachers Methods course (may be taken under the Department of Education)
After completing this basic program, teachers intending to teach grades seven, eight, or nine should choose three or more courses from the following:
Foundations of Mathematics
Additional courses in Abstract Algebra
Additional courses in College Geometry
(other than Analytic Geometry)
Number Theory
Logic
History of Mathematics
Probability and Statistics
A teacher intending to teach grades ten, eleven, or twelve should complete integral calculus and choose three or more courses from the following:
Foundations of Mathematics
Additional courses in Abstract Algebra
Additional courses in College Geometry
(other than Analytic Geometry)
Number Theory
Logic
History of Mathematics
Probability and Statistics
Additional Calculus courses
