No full textSUMMARY Requirements of hospital care and nursing features in patients with intestinal stomas Master Final Work by Nursing Department Student Turba Ž. Research Adviser–Docent Simutis G. Vilnius University, Medical Faculty, General Medicine Practice and Nursing Department Vilnius, June 14, 2006 The problems of patients with intestinal stomas and the requirements of their care after surgery are the major questions in the nursing nowadays. Aim of the investigation: to define the hospital care needs and nursing features for patients who underwent surgery with the formation of intestinal stomas. Tasks of the investigation: 1. To define problems during early postoperative period after stoma formation using the method of survey. 2. To analyze the expectations of patients after stoma formation. 3. To evaluate if the nursing services are efficient for patients after intestinal stoma formation. 4. To define nursing features after intestinal stoma formation. 5. To evaluate the competence of nurses in providing care for patients with intestinal stoma formation. The methods of survey using two questionnaires and statistic analysis of documents were used. 30 patients with intestinal stomas and 64 nurses of surgical departments in Vilnius hospitals were questioned. The analysis of 73 cases was performed. Results and conclusions: 1. The most common problems after intestinal stoma formation are fear and concern with the quality of life (70%), postoperative pain (67%), lack of knowledge of stoma care (50%). The problems of surgical wound and stoma care are more frequent for patients with permanent intestinal stomas than temporary intestinal stomas. 2. Lack of attention to patients psychological rehabilitation (8%). Some patients would prefer more respect (40%), attention and time for socializing (20%) as well as moral support (7%). These problems are more common to people who have university degree or higher education. 3. The lack of postoperative patient teaching (27%). Most patients need more information about stoma care (93%), they would like better teaching (43%). Two thirds of patients do not get enough information on feeding after operation (73%). One third of patients do not know what kind of stoma they have (30%). Most patients lack information about social life having a stoma (57%). 4. Two thirds of patients need further nursing care at home (70%), especially patients with permanent stomas. According to nurses the main nursing features are: skin care around stoma, proper use of stoma care products (89%), the teaching of personal care after operation (66%), Information on daily life (30%). 5. The nursing problems after intestinal stoma formation are: lack of time due to high work intensity, lack of psychological knowledge and stoma nursing features and lack of stoma care products
SandP500 index stock ranking algorithm development and testing.
No full textInvestors in stock markets are searching for computer software tools to analyze and rank stocks to make investment decisions. The analysis tools fall into two main groups: tools for fundamental analysis and tools for technical analysis of stock. In the current paper the author is looking for ways to combine fundamental and technical analysis to make better investment recommendations. Special emphasis is on money management rules used to open positions, calculate position size for each stock and overall portfolio value. Author also explains how to apply money management rules to not lose money in the markets. The object of this paper is S&P500 index stock ranking algorithms. The aim of the paper is to develop and test new stock ranking algorithms based on both technical and fundamental indicators. Money management rules is also a critical part selecting stocks and creating stock portfolios. In part 1 of the paper the reasons why each investor should you use both fundamental and technical analysis in his or her trading, and the importance of proper money management is explained. Author also writes about advantages using system trading instead of discretional trading. In part 2 of the paper the expert system is described. In part 3 of the paper the expert system is tested by analyzing S&P500 index stock and making trading decisions to form a stock portfolio. The expert system was tested for two weeks after is has been completed. Results of the system testing are analyzed and explained. This MBA paper consists of introduction, three parts, conclusion and annexes. The material is discussed in 65 pages, including 8 tables and 58 pictures, and 4 annexes
Toward a Writing Theory of Transition
No full textThis dissertation uses the spiral metaphor to explore writing experiences and begins to formulate a wider conception of writing transitions by following three experienced writers as they move across settings. Based on their texts, the stories of their experiences, and the stories of others involved in their writing tasks, I argue that the phases of transition, as defined by transitional dynamics and organizational socialization, affect writing only in certain circumstances. There appear to be many other sites of divergence where writers, readers, texts, and contexts fail to reach their targeted communication. The difficulties that arise from these sites point to aspects of writing situations that should be included in any discussion of transitional problems. In addition, sites of convergence reveal how writers in transition prepare for change, enlist the support of both personal and professional networks, and learn to manage writing tasks in new settings. Understanding the problems of writers in transition, I further argue, requires that researchers focus on myriad divergent sites in both former and new settings and not simply the linear progression of change.Made available in DSpace on 2015-09-25T20:15:37Z (GMT).

Realization of Human Skill Based “Break Out” Trading Strategies Using Fuzzy Logic Methods
No full textUniversal fluctuating regime in triangular chromate antiferromagnets
No full textWe report x-ray diffraction, magnetic susceptibility, heat capacity, H-1 nuclear magnetic resonance (NMR), and muon spin relaxation (mu SR) measurements, as well as density-functional band-structure calculations for the frustrated S = 3/2 triangular lattice Heisenberg antiferromagnet (TLHAF) alpha-HCrO2 (trigonal, space group: R (3) over barm). This compound undergoes a clear magnetic transition at T-N less than or similar to 22.5 K, as seen from the drop in the muon paramagnetic fraction and concurrent anomalies in the magnetic susceptibility and specific heat capacity. Local probes (NMR and mu SR) reveal a broad regime with slow fluctuations down to 0.7 T-N, this temperature corresponding to the maximum in the mu SR relaxation rate and in the NMR wipe-out. From the comparison with NaCrO2 and alpha-KCrO2, the fluctuating regime and slow dynamics below T-N appear to be hallmarks of the TLHAF with ABC stacking. We discuss the role of interlayer frustration, which may have impacted recent spin-liquid candidates with triangular geometry.This article is published as Somesh, K., Y.

No full textViable cell estimation of mammalian cells using off-gas-based oxygen uptake rate and aging-specific functional /
No full textThis study developed an estimation routine for counting the viable cells in an in vitro fed-batch Chinese hamster ovary cultivation that relies on off-gas information and inlet gas mixture knowledge. We computed the oxygen uptake rate bound to the bioreactor exhaust gas outlet when the inlet gas mixture was stationary. Our mammalian biosynthesis analysis determined the stoichiometric parameters as a function of the average population age. We cross-validated an identical algorithm for mammalian and microbial cultivations and found that the' 99% confidence band of the model generally overlapped with the error bars defined from observations. The resulting RMSE and MAE averages were 0.188 and 0.14e9cells L-1, respectively, when estimating the viable mammalian cell count. The validation for the estimation of total bacterial biomass yielded an MAE and RMSE of 1.78 g L-1 and 2.53 g L-1, respectively. Moreover, our proposed approach provides an online estimation of the average population age for both aerobically cultivated microorganisms
Fuzzy Expert System for a Stock Trading Process
No full textThe goal of this study was to build and to evaluate a human skill based fuzzy expert system for a decision making support in stock trading process. Our focus was concentrated on Computer software that is capable to reproduce the knowledge from the skilled stock trader. Using classical technique and soft computing methods the expert system STRASS (Stock TRAding Support System) was developed. The proposed system was tested for the historical collection of NASDAQ, NYSE and AMAX stock records. At present, it is being tested by "KOLEGU" mutual fund in a real stock trading process. Key words – fuzzy expert systems, stock trading process, evolutionary programming
Blyksnio sužadintų potencialų klasifikavimas naudojant dirbtinį neuronų tinklą.
No full textThis paper presents how the certain sequences of the light impulses (or narrows squares) can be used to increase the number of commands for a brain-computer interface which is based on visually evoked potentials. The observation of the certain components in the power spectrum of the measured EEG will not give needed results, because the blink of the stimulators is not periodic. Therefore, different methods must be used to recognize a user commands. In this paper, a classification of flash visual evoked potentials (FVEP) of visual cortex which is induced by OFF-to-ON flash of light source based on artificial neural network is presented. The presented below results shows that is possible two classify EEG signals, which were recorded when person was visually stimulated with two type’s stimuli
