Patterns of self-disclosure in psychotherapy and marriage.

This study compared patterns of self-disclosure in psychotherapy and marriage. Participants (48 married, current psychotherapy patients, mean age = 42) completed a 101-item Disclosure to Therapist Inventory and a companion measure, a 101-item Disclosure to Spouse Inventory. Results indicated a pattern of greater disclosure to one's therapist in regard to issues involving despair (e.g., feelings of depression), and to one's spouse in regard to procreation and body concerns (e.g., birth control) and values (e.g., feelings about religion, race, or politics). Issues involving sex were infrequently discussed in either context. Discrepancy scores (differences between extent of disclosure and perceived importance) were greater in the spouse condition. Outcome predictors varied by situation, with overall disclosure predicting therapeutic outcome and both overall disclosure and discrepancy scores predicting marital satisfaction. Findings suggest that although there is substantial overlap in issues discussed in these two contexts, certain intimate disclosures are perceived as situation-specific.

Modified Notch Filter-based Instantaneous Phasor Estimation for High-speed Distance Protection

A novel method for estimating the instantaneous phasor of a fault current signal is proposed for high-speed distance protection immune to a DC-offset. The method uses a modified notch filter in order to eliminate the fundamental frequency component from the fault current signal. Since the output of the modified notch filter is the delayed DC-offset, delay compensation results in the same waveform as the original DC-offset. Subtracting the obtained DC-offset from the fault current signal yields a sinusoidal waveform, which becomes the real part of the instantaneous phasor. The imaginary part of the instantaneous phasor is based on the first difference of the fault current signal. Since a DC-offset also appears in the first difference, the DC-offset is removed from the first difference using the results of the delay compensation. The performance of the proposed method was evaluated for a–phase to ground faults on a 345 kV 100 km overhead transmission line. The Electromagnetic Transient Program was used to generate fault current signals for different fault locations and fault inception angles. The performance evaluation showed that the proposed method can estimate the instantaneous phasor of a fault current signal with high speed and high accuracy. The paper concludes by describing the hardware implementation of the proposed method on a prototype unit based on a digital signal processor.     

Intradermal and subcutaneous leiomyosarcoma: a clinicopathological and immunohistochemical study of 41 cases

Superficial leiomyosarcomas are rare tumours. The lesions confined to the dermis, contrary to those involving the subcutis, have been reported to carry a favourable prognosis. A retrospective study of 41 consecutive cases of surgically treated intradermal and subcutaneous leiomyosarcomas was undertaken in order to determine the prognostic factors that may influence the survival of these patients. Seven tumours were predominantly intradermal and 34 involved the subcutaneous tissue. Fifty-four percent of the tumours were located in the lower extremities. All cases stained positively for smooth muscle antigen and 66% for desmin. The tumours were classified with regard to tumour grade I (low grade, 3%), II (intermediate, 12%), IIIA (high grade, 46%) and IIIB (high grade, 39%). In all patients, follow-up information was available. Mean follow-up time was 5 years. The patients with intradermal tumours were all alive without signs of recurrence, whereas 14 of those with leiomyosarcomas involving the subcutis have died with pulmonary metastases. Our study confirms that "pure" intradermal leiomyosarcomas independent of tumour grade behave in a benign fashion, probably due to small tumour size. Tumour size > or = 5 cm, deep localization with fascia involvement, and high malignancy grade (IIIB) were found to deteriorate survival based on a univariate analysis. However, in a multivariate analysis only tumour size was found to be an independent prognostic factor.     

The pathogenetic basis for detoxifying and antioxidant therapy in the combined treatment of chronic diffuse liver diseases

As many as 98 patients with chronic diffusive liver diseases were studied for markers of endogenous intoxication syndrome as they were for intensity of lipid peroxidation (LPO) processes, condition of the antiradical defence systems, and detoxicating effectiveness of the drug "Thiotriasoline". Revealed in the patients were intensification of LPO processes, enhancement of the glutathionic system enzymes activity, decrease in superoxide dismutase. Accumulation in blood of malonic dialdehyde and molecular LPO products is believed to be a factor of the endogenous intoxication syndrome progression. A correlation was found between activity of LPO processes, intensification of endotoxicosis and degree of activity of the inflammatory process in the liver. The results obtained attest to the need for the antioxidant and adequate detoxicative therapy. High detoxicating efficacy of the drug "Thiotriasoline" has been shown.     

Conceptual approaches to the diagnosis of stress-induced functional disorders in humans under conditions of industrial activity

In accordance with the fundamental concept of the systems symmetrical approach, a model of the body's "ideal functional status" and a polyparametric method for diagnosing the human functional status (the method has been patented in Russia) were developed, on the basis of the unified set of amplitude and time parameters of a complex of physiological parameters (ECG, etc.). The systems symmetrical approach is basically new in defining the ratio of harmonic parameters acting as new diagnostic evidence for the health status. The unchanging ratio of parameters of autovariation processes in the cardiac, vascular, and respiratory systems, their changes in the development of the adaptative syndrome and the value were examined in healthy individuals at rest and during exercise an intensive productive activity (point brazing at a plant of electron devices), and in the trainees. It was demonstrated that the mechanism of development of adaptative processes was associated with the synchronization of autovariations in the cardiorespiratory and vascular systems and the involution of adaptative processes, their break, depletion, i.e. stress, were determined by the imbalance of relationships and the desynchronization of autovariations in these systems. To define a set of cardiorespiratory and hemodynamic parameters is necessary, but insufficient to evaluate (diagnose) the health status and health-disease intermediate diseases (stress and adaptative overtension). The ratio harmonicity of these parameters, i.e. well-balanced relations between the subsystems is the main characteristic. The assessment of the human health status in terms of the reference-the model of the ideal status as the ideal health status without using the complex and indefinite concept of the normal and moderate health status-is conceptual for polyparametric status estimation.     

Transient temperature responses of hydronic radiant floor heating system by different pipe embedding depth and water supply condition

"Ondol" is a Korean unique heating system. It is a specific radiant floor heating system using combustion heat of briquette or timber in Korea. Such traditional "Ondol" is changed to radiant heating system with pipe-coil embedded in the floor or slab. This study has contributed to the understandings of the transient behaviours of Ondol-heated floor panels and enclosure exposed to this type of heating system. The result is that the water supply temperature had a large effect on the rate of increase in floor surface and room air temperature. But, in spite of a higher water supply temperature, the heat flow rate was not increased considerably. The shallow pipe embedding depths, of course, result in a low heat flow rate.     

Numerical investigation on the heat transfer characteristics of a liquid-metal pool subjected to a partial solidification process

The main purpose of this paper is to investigate numerically the effects of solidification on the heat transfer characteristics of the liquid metal layer, for use in accident analyses. The situation is very similar to an overlying liquid melt pool that could be fooned in the reactor lower head during the late phase of a severe nuclear accident. Based on a computational model, MPCOOL, the numerical predictions were then assessed through a comparison with the experimental data that was obtained with various boundary temperature conditions and geometrical aspect ratios, especially for the Ra-Nu relationship. For the cases with solidification, the results of the comparison show that(a) the computational model does show a good agreement with heat transter rates inferred from the experimental data, with a few exceptions at the Ra numbers which suggest a turbulent transport; and also (b) the computational model underpredicts the heat transfer rates by about 6% than that inferred from the experimental data when it is integrally evaluated with the Ra-Nu correlation. The foregoing results are mainly due to the currently limited applicability of the computational model up to the laminar-to-turbulence transition flows and its application to the turbulence flows because it is always subjected to a model uncertainty between the laminar and turbulence. Next, an additional comparison for the cases with and without solidification was made to examine the effects of the solidification on the energy partition within the liquid metal layer and its effects on the directional heat transfer rates. The results of the comparison show that the computational model for the case without solidification predicts higher heat transfer rates by about 15% than when solidification is included, but there isn't any experimental data that directly supports this trend.     

On the Rate Expressions for “Reversible” Gas–Solid Reactions

It is argued that the term with the negative sign in the rate expression for an equilibrium-limited gas–solid reaction can be viewed as representing a lowering of the concentration driving force for the forward reaction due to equilibrium limitation. While the gas composition favors the forward reaction, the negative term may represent the local rate of the reverse reaction. When the gas composition changes significantly to the opposite side of equilibrium, however, this term as written for the forward reaction does not represent the rate of the reverse reaction. Even the reaction order with respect to the same gaseous species may become different for the reverse reaction.
