Authors: Popczyk Magdalena , Łosiewicz Bożena , Łągiewka Eugeniusz , Budniok A.
Published: March 2015

The Ni+W+Mo+Si composite coatings were prepared by electrodeposition under the galvanostatic conditions (jdep= -100 mA cm-2) from the nickel bath containing powders of tungsten, molybdenum and silicon. Thermal treatment of the obtained coatings was conducted in argon atmosphere. Chemical composition of the coatings was determined by energy dispersive spectrocopy (EDS). Phase composition investigations were conducted by X-ray diffraction (XRD) method. Studies of electrochemical corrosion resistance were carried out in 5 M KOH solution. On the basis of these investigations it was found that Ni+W+Mo+Si thermally treated coating is more corrosion resistant than Ni+W+Mo+Si as-deposited coating.

Authors: Łosiewicz B. , Popczyk Magdalena , Szklarska Magdalena , Osak Patrycja
Published: March 2015

The electrodeposited Ni-P coatings are commonly used for their electrocatalytic properties towards hydrogen evolution reaction. However, their corrosion resistance in concentrated alkaline solutions is still less known. In this work, the effect of phosphorus on the resistance of nickel electrodeposits to electrochemical corrosion in 5 M KOH solution, was studied. Open circuit potential and anodic polarization measurements were performed to determine parameters of the corrosion resistance of the crystalline Ni deposit and amorphous Ni-P electrocoating. It was found that alloying of nickel with phosphorus is the effective manner of the improvement of the corrosion resistance of the nickel coatings. The obtained Ni-P electrode material contained 10 wt.% of P and revealed amorphous structure. The increase in the corrosion resistance of the Ni90P10system as compared to that determined for comparable Ni polycrystalline electrode was due to phosphate formation responsible for broad passivation potential in alkaline medium and amorphous structure.

Authors: Łosiewicz Bożena , Dercz Grzegorz , Popczyk Magdalena
Published: March 2015

Versatile applications and broad interest in amorphous electrode materials, especially the nickel-phosphorus coatings, primarily results from their unique properties and low-production costs in comparison to precious metals. This paper discusses the most important research conducted over several years into the Me-P layers, in particular the Ni-P and Ni-Me-P ones, which led to only partial understanding of these amorphous alloys. Methods of increasing the catalytic activity of the Ni-P layers in the process of electroevolution of hydrogen are also discussed because the electrolytic layers of amorphous nickel still seem to be the promising electrode material.

Authors: Łosiewicz Bożena , Popczyk Magdalena , Szklarska Magdalena , Smołka Agnieszka , Osak Patrycja , Budniok A.
Published: March 2015

This work presents the basic theory and the usability of the scanning vibrating electrode technique (SVET), especially in the field of corrosion. At present, SVET is to be considered as one of the latest electrochemical testing methods. The essence of determining the current density resulting from corrosion is limited to the measurement of the potential gradient between the two points on the surface of the metal and over it, within the electric field of a local element. SVET has been used to study local, galvanic and intercrystalline corrosion. It is particularly useful in studying the corrosion of alloy steels and welding agents. This paper presents a review of the literature on the newest research in this field.

Authors: Łosiewicz B. , Popczyk Magdalena , Szklarska Magdalena , Smołka Agnieszka , Osak Patrycja , Budniok A.
Published: March 2015

This paper deals with the basic theory and the usability of the scanning Kelvin probe (SKP) being a non-destructive, non-contact method for testing the condition of the surface of conductor, semiconductor and dielectric samples. This technique is based on the electron work function (EWF) characteristic of various test substances and depends, inter alia, on the sample surface condition. During measurement, the so-called surface potential distribution map containing information about EWF value is registered. Key applications of SKP and its various modifications to characterization of corrosion interfaces, have been presented based on the newest literature data covering the past two years of the active research in the field of corrosion in a nanoscale.

Electrodeposition Mechanism of Composite Coatings
Authors: Łosiewicz Bożena
Published: March 2015

The mechanism of co-deposition of solid particles with metal ions has not been thoroughly explained so far. This, among others, results from a number of factors that influence the process and their mutual relations. Therefore, the present paper aims at deeper understanding of the mechanism of electrolytic co-deposition and the mathematical models developed over the years to describe the incorporation of solid particles into electrodeposited metals. In this review, three mechanisms explaining the process of co-deposition of solid particles with the metal matrix have been discussed: (i) the electrophoretic, (ii) the mechanistic, and (iii) the adsorption ones.

Authors: Szklarska Magdalena , Smołka Agnieszka , Popczyk Magdalena , Łosiewicz Bożena
Published: March 2015

Electrodeposition of polycrystalline nickel onto carbon steel substrate has been studied from different types of solutions: (bath I) the Watts nickel plating bath, (bath II) the sulfate-chloride nickel plating bath for production of the SUPER Ni coatings, (bath III) the sulfamate nickel plating bath, and (bath IV) the chloride nickel plating bath. A detailed study has been made on the influence of the bath composition on the mass increment and thickness of the deposited Ni coatings. Cathodic current efficiency of the Ni electrodeposition has been also studied. The electrochemical anodic de-plating technique has been used for measuring the thickness of nickel coatings according to ISO 2177:2003. Evaluation of the effect of bath composition on the quality of the galvanic nickel coatings, was carried out using the Hull cell. In a single test, the range of current densities which provided a desired plating characteristic at a given total current, was previewed. Principles of the electroplating process using the Hull cell have also been explained.

Authors: Łosiewicz B.
Published: March 2015

This study reports on Ni (II) ion adsorption onto TiO2powder of different concentration in suspension baths developed for electrodeposition of composite Ni-P+TiO2coatings. The experimental results were modeled with the Langmuir, Freundlich and Temkin adsorption isotherms. It was found that the best fit of Ni (II) ion adsorption data was obtained using the Langmuir isotherm. The study also revealed that adsorption of the nickel ions is a function of TiO2adsorbent dose in bath. The role of Ni (II) ion adsorption onto TiO2adsorbate in the elctrodeposition process of composite Ni-P+TiO2coatings was discussed.

Efficacy of intravenous immunoglobulin monotherapy in patients with cutaneous lupus erythematosus: results of proof-of-concept study
Authors: Ky Christa , Swasdibutra Brian , Khademi Shaadi , Desai Sheetal , Laquer Vivian , Grando Sergei A.
Published: March 2015

Cutaneous lupus erythematosus (CLE) is a chronic inflammatory autoimmune skin disease. Evidence-based therapy for CLE is lacking in the most part. Intravenous immunoglobulin (IVIg) is being increasingly utilized as off-label therapy for a variety of autoimmune and inflammatory conditions, especially in dermatology. The usefulness of IVIg in CLE is not well established. The goal of the present study was to obtain the proof-of-concept evidence that IVIg can control acute CLE and thus replace current systemic immunosuppressive therapy that causes severe side effects and adverse reactions. Sixteen patients who tried and failed various systemic treatments for CLE were screened and consented to use IVIg as a monotherapy. The IVIg was administered at 500 mg/kg/day on 4 consecutive days up to a total of 2 g/kg/month for 3 months, and the subjects were monitored for additional 6 months off any drug for a possible relapse. The cumulative results revealed an overall improvement, as evinced by a decrease of both objective and subjective measures of disease activity. The most sensitive and specific objective and subjective instruments for assessment of the therapeutic effect of IVIg were CLASI-A (Cutaneous Lupus Erythematosus Disease Area and Severity Index) measuring disease activity and Skindex-29 scores, respectively. The CLASI-A score dropped down from the initial value taken as 100%, and remained in the range of approximately 70% until the last visit. Three patients (18.8%) had a temporary flare of CLE symptoms but recovered within a month from the relapse. No serious side effects and adverse reactions occurred. Thus, IVIg monotherapy in CLE allowed to achieve: i) rapid and persistent decreased in disease activity; ii) steady improvement of patients’ quality of life assessed by Skindex-29; iii) low relapse rate; and iv) mild nature and short duration of relapses. Since healing was maintained for months after IVIg treatment, it is possible that the IVIg-triggered molecular events mediating the therapeutic action of IVIg that continued to unfold after the end of therapy.

Delayed immune mediated adverse effects to hyaluronic acid fillers: report of five cases and review of the literature
Authors: Bitterman-Deutsch Ora , Kogan Leonid , Nasser Faris
Published: March 2015

Hyaluronic acid (HA) fillers in cosmetic medicine have been considered relatively safe, though fillers used in European countries and throughout the world are not necessarily approved by the Food and Drug Administration. As their use continues to expand worldwide, physicians in a wide range of medical specialties are authorized to perform HA injections, including general medicine practitioners and even dentists. An increasing number of reports have appeared regarding side effects to these products. It is now known that reactions to Hyaluronic acid are related not only to technical faults of the injections, but also to immune responses, including delayed hypersensitivity and granulomatous reactions. Herein, we describe five cases treated by a variety of treatment modalities, all with delayed reactions to different brands of hyaluronic acid fillers. As there is currently no standardization of treatment options of adverse effects, these cases accentuate the debate regarding the approach to the individual patient and the possible need for pre-testing in patients with an atopic tendency.
Ficus sur (Moraceae) and Gymnanthemum coloratum (Asteraceae: Vernonieae) – first distribution records for Namibia
Authors: Swanepoel Wessel , Van Jaarsveld Ernst J.
Published: March 2015

Background: The distribution of Ficus sur includes most of tropical Africa, but whilst this species was suspected to occur in Namibia, this has not been verified. Gymnanthemum coloratum is a tropical African savannah shrub or tree that has been recorded for Botswana, Swaziland and South Africa, but which has not previously been recorded for Namibia.Objectives: To formally document the first records of two plant species from Namibia and provide habitat details of the localities from which these species were recorded.Method: The data presented have resulted from botanical expeditions to the poorly known Baynes Mountains in the Koakoveld region of Namibia. Specimens of the two species in the National Herbarium, Pretoria were examined to verify the identity in the case of G. coloratum, and to document additional records in Namibia for F. sur.Results: Ficus sur was recorded from two localities, and a third locality based on a specimen in the National Herbarium, Pretoria, was verified. Gymnanthemum coloratum, a member of the Asteraceae, was recorded from a single locality.Conclusion: The fact that F. sur was collected at more than one location in the Kaokoveld suggests that it is probably more widespread in suitable microhabitats. Ficus sur also occurs further north in Angola, suggesting that the Kaokoveld plants represent a cross-border outlier of the much more widespread Angolan population. Gymnanthemum coloratum was only recorded from the one locality in the Koakoveld. The species also occurs in Angola, which suggests that the Kaokoveld plant represents a cross-border outlier of the population in that country.

Authors: Nicholas Deanne L. , Gillan Wayne D.H.
Published: March 2015

The meibomian glands of the upper and lower eyelids play a valuable role in secreting the lipidlayer of the tear film. Disturbances in meibomian gland function may result in altered secretion andvariations in tear composition which may lead to meibomian gland dysfunction and evaporativedry eye, leading to ocular discomfort. To diagnose and monitor the structural and functionalchanges occurring within the glands of the eyelids, various imaging techniques are available.Some of the methods used to evaluate the tears and therefore the meibum within the tears includeevaporimetry, interferometry, tear osmolarity and meibometry. With these techniques, changesin the lipid layer of the tear film can be quantified and alterations in meibomian gland functionassessed. Meibography is an additional method that can be used; it has the unique feature ofallowing the assessment of meibomian gland morphology during ocular surface disease processes.The aim of this review is to create an improved understanding of the meibomian glands and theways that they may be investigated in order to expand on the treatment methods available.

Die Semeia [tekens] in die Evangelie volgens Johannes
Authors: Schnelle Udo
Published: March 2015

Die semeia in die Evangelie van Johannes word eerstens geanaliseer in verhouding tot soortgelyke wonderverhale, veral in die sinoptiese evangelies en ten tweede in verhouding tot die breër Johannese narratief. Duidelike ooreenkomste met sommige van die sinoptiese wonderverhale word bespreek. Dit lei tot die bevraagtekening van die sogenaamde ‘semeia-bron’-teorie. Opvolgend op hierdie diskussie word Johannes se eie interpretasie van die wonders nagegaan. Daar word veral aan die vervlegting van die wonderverhale met die teologie van Johannes aandag gegee, veral ten opsigte van die verhouding tussen die Vader en die Seun, geloof, die menslikheid van Jesus en die lyding van Jesus.The Semeia in the Gospel according to John. The semeia in the Gospel of John are analysed, first in relation to other similar miracle narratives, especially in the synoptic gospels, and secondly in perspective of the broader narrative of John’s Gospel. Clear links with some of the synoptic miracle narratives are discussed, questioning the ‘semeia source’ theory. This discussion is followed by a consideration of John’s own interpretation of the miracles, exploring the interwovenness of the miracle stories with the theology of John, especially regarding the relation between the Father and the Son, the humanness of Jesus, the passion of Jesus and faith.
’n Prinsipiële diskoers oor die epistemologiese fundering van die Pastorale Teologie: ’n Oproep tot reformasie
Authors: Janse van Rensburg Johan
Published: March 2015

Hierdie artikel is as ’n huldeblyk aan prof. George Lotter by sy aftrede geskryf en uit erkenning vir sy bydrae tot die wetenskapsbeoefening van die Praktiese Teologie. Die artikel ondersoek die huidige konteks van die pastorale teologie. Aangesien epistemologiese keuses die metodiek en uitkoms van die pastoraat bepaal, is daar ’n dringende noodsaak om die epistemologiese invloede op die pastorale teologie te evalueer. Die artikel fokus op die epistemologiese dinamika wat die pastoraat verander het van ’n skriftuurlike fundering na ’n kommunikatiewe handelingsteoretiese en postmoderne narratiewe strategie. Die navorsingsvraag is: Is ’n reformatoriese terugkeer na ’n bybels-gefundeerde pastoraat teen die agtergrond van die epistemologiese invloede nog moontlik?As a tribute to Prof. George Lotter on the occasion of his retirement and to his contribution to practical theology, this article focuses on the current situation of pastoral theology worldwide but mostly in South Africa. Since epistemological choices determine the method and content of research on pastoral theology, as well as the practical implementation thereof, there is an urgent need to evaluate the influences on pastoral theology and the results of these influences. The article focuses on the epistemological dynamics that have changed pastoral theology from a scriptural approach to a discipline of communicative acts and a postmodern strategy of narrative pastoral counselling. The research question is: Is it still possible to have a reformed pastoral theology and pastoral counselling against the backdrop of these epistemological changes?
An inventory of epigeal ants of the western Soutpansberg Mountain Range, South Africa
Authors: Munyai Thinandavha C. , Foord Stefan H.
Published: March 2015

The distribution, abundance and sensitivity invertebrates to habitat change are largely unknown. Long-term monitoring of ecological gradients with standardised and comparable protocols can form the basis of a better understanding. Altitudinal gradients are particularly relevant within this context. Here we provide a check list and baseline data for ant species collected over a 5-year period across the Soutpansberg Mountain Range, South Africa. Standardised pitfall surveys across 11 sites yielded a total of 133 species in 38 genera and 6 subfamilies. Sample coverage of epigeal ants was 0.98 for the transect as a whole. Of these species, 21% were restricted to the southern slope of the mountain and 14% to the northern slope. Extrapolated richness estimates reached an asymptote for all, except for three sites. These were the only sites impacted by bush encroachment. Observed richness was the highest at a low-altitude mesic site that is exposed to considerable disturbance by megaherbivores and mechanical clearing of woody vegetation. Structural classification of vegetation was predictive of a broad-scale ant assemblage structure. On a smaller scale, however, structure was a function of elevation, space and temperature.Conservation implications: Future monitoring should target indicator taxa associated with bush encroachment, particularly with reference to their impacts on grasslands. Bush encroachment could endanger several ant species associated with mesic grasslands and woodlands on the mountain, as well as ant diversity, as these were the habitats with the highest ant diversity.

Current research in the area of wellness in the workplace is fragmented and requires a holistic, integrated and systemic understanding of employee wellness in order for health and wellness care to be effectively managed. The growing burden of noncommunicable conditions in South Africa highlights the necessity for prevention strategies such as wellness programmes to be implemented. The workplace provides an ideal setting as a large proportion of the population will be targeted, including those who require lifestyle improvement. Therefore this study sought to evaluate various health and wellness components among employees of a medical aid company in an attempt to identify risk areas which require further intervention. Participants were 140 employees of a medical aid company who work a minimum of 40 h per week and who were subjected to a wellness assessment battery, consisting of anthropometrical, health-related and physical capacity measurements. The results indicate that intervention is required in terms of alcohol and drug usage, dietary habits, heart health, body composition, muscular endurance, cardiorespiratory endurance, and individual perceptions towards the company. This study produced results which corroborate the findings of a great deal of previous research in this field. However, the scope for applying wellness programmes to the South African population is limited. The success of wellness programmes which emphasise physical activity has been well documented in high-income countries, with evidence of economic benefits and return on investment. And so it is proposed that implementation of wellness programmes will have a positive effect on the South African workforce.

Published: March 2015

Chemotherapy regimens, including doxorubicin used in primitive neuroectodermal tumor′s (PNET) treatment can cause life-threatening disorders in cardiac functions. Follow-up of cardiac functions in the clinical course is very important during treatment with ejection fraction (EF) and shortening fraction (SF). However, sometimes the detection of cardiac failure with EF and SF cannot be possible. In this condition, we may need new evaluation test. Herein, we wanted to present a child with PNET of the chest wall suffered from antracycline toxicity and indicate that close monitoring of cardiac function could be important.

Published: March 2015

Several studies have reported on the expression of somatostatin receptors (SSTRs) in patients with differentiated thyroid cancer (DTC). The aim of this study was to evaluate the imaging abilities of a recently developed Technetium-99m labeled somatostatin analog, 99m Tc-Hynic-TOC, in terms of precise localization of the disease. The study population consisted of 28 patients (16 men, 12 women; age range: 39-72 years) with histologically confirmed DTC, who presented with recurrent or persistent disease as indicated by elevated serum thyroglobulin (Tg) levels after initial treatment (serum Tg > 10 ng/ml off T4 suppression for 4-6 weeks). All patients were negative on the Iodine-131 posttherapy whole-body scans. Fluorine-18 fluorodeoxyglucose positron emission tomography ( 18 F-FDG PET) was performed in all patients. SSTR scintigraphy was true positive in 23 cases (82.1%), true negative in two cases (7.1%) and false negative in three cases (10.7%) which resulted in a sensitivity of 88.46%, specificity of 100% and an accuracy of 89.2%. Sensitivity of 99m Tc-Hynic-TOC scan was higher (93.7%) for patients with advanced stages, that is stages III and IV. 18 F-FDG showed a sensitivity of 93.7%, a specificity of 50% and an accuracy of 89.3%. 18 F-FDG PET was found to be more sensitive, with lower specificity due to false positive results in 2 patients. Analysis on a lesion basis demonstrated substantial agreement between the two imaging techniques with a Cohen′s kappa of 0.66. Scintigraphy with 99m Tc-Hynic-TOC might be a promising tool for treatment planning; it is easy to perform and showed sufficient accuracy for localization diagnostics in thyroid cancer patients with recurrent or metastatic disease.

Authors: Bharadwaj Suparna , Moga Rebecca , Manninen Pirjo , Venkatraghavan Lakshmikumar
Published: March 2015

Pre-surgical embolization of vascular brain and spinal tumours is an effective method of reducing intraoperative bleeding. Many technological developments of the microcatheters and embolic materials that are used have led to better outcomes in tumour embolization. Pre-operative embolization has become a standard of practice in the management of many vascular brain and spinal tumours. Anaesthesiologists are generally involved with these procedures which may be performed with general anaesthesia, conscious sedation or monitored anaesthesia care. The choice of the anaesthetic technique usually depends on the patient characteristics, tumour location, vascularity of the tumour and most importantly the neuroradiologist and/or institutional preferences. There is limited information in the literature on the anaesthetic considerations for these patients. The aim of this review is to provide a brief overview of the indications, techniques, complications and relevant anaesthetic considerations for patients undergoing pre-surgical embolization of intracranial and spinal tumours.
Current neuromonitoring techniques in critical care
Authors: Ristic Anette , Sutter Raoul , Steiner Luzius
Published: March 2015

Early detection of secondary events is a major target of neuromonitoring in critically ill patients. Intracranial pressure (ICP) and cerebral perfusion pressure are the most widely accepted neuromonitoring parameters. Many studies have shown both to be related to mortality after traumatic brain injury. However, the benefit of ICP monitoring has not been established by a randomized controlled trial, and the efficacy of ICP-guided management has indeed been challenged. This review considers current neuromonitoring techniques in critical care medicine.
To compare the effects of multiple sessions of Hyperbaric Oxygen Therapy in neurological improvement in head injury patients: A prospective randomized trial
Authors: Yadav Amlendu , Pawar Mridula , Garg Rakesh , Banerjee Neerja
Published: March 2015

Introduction: Hyperbaric oxygen therapy (HBOT) is used to improve functional outcome following brain injuries. Different number of sessions of HBOT have been reported but the frequency of HBOT sessions in head injured patients has not been standardized. We planned this prospective randomized study with an aim to compare the neurological effects of 10, 20 and 30 sessions of HBOT in the head injured patients. Materials and Methods: After review board approval, this study was conducted in 60 head injury patients with Glasgow Coma Scale (GCS) score ≤ 9. All patients were resuscitated, stabilized and received neurological care according to institutional protocol. Patients were randomly allotted to–Group H10 (n-20)–which received 10 sittings of HBOT, Group H20 (n-20)–which received 20 sittings of HBOT, Group H30 (n-30)–which received 30 sittings of HBOT. GCS score was recorded after every 10 sittings and at 30 days from initiation of HBOT. Improvement Global rating and Glasgow outcome scale (GOS) were recorded after 30 days. Results: The maximum improvement in GCS scores was seen in group H30. The difference in the average improvement global rating scale was significant between group H10 and group H20, between group H10 and group H30 but was comparable between groups H20 and H30. The GOS was better after 30 sessions as compared to 10 sessions. Patients of all groups showed improvement in spasticity but group H30 showed a maximum improvement. Conclusion: A minimum of 30 HBOT sessions should be considered in head injury patients to show improvement with HBOT. Progressive improvement in GCS scores, GOS, spasticity, mood swings was better seen with increased number of HBOT sessions.
Cardiogenic oscillation induced ventilator autotriggering
Authors: Kaloria Narender , Gupta Akhilesh , Goila Ajay , Sood Rajesh
Published: March 2015

Cardiogenic oscillation during mechanical ventilation can auto-trigger the ventilator resembling patient initiated breadth. This gives a false sense of intact respiratory drive and determination brain death, even if other tests are positive, is not appropriate in such a situation. It will prolong the ICU stay and confound the brain-death determination. In this case report, we describe a 35 year old man who was brought to the hospital after many hours of critical delay following multiple gun shot injuries. The patient suffered a cardiac arrest while on the way from another hospital. After an emergency laparotomy, patient was shifted to Intensive Care Unit (ICU) with Glasgow Coma Scale (GCS) score of E1VTM1 and was mechanically ventilated. Despite absence of brainstem reflexes, the ventilator continued to be triggered on continuous positive airway pressure (CPAP) mode and the patient maintained normal oxygen saturation and acceptable levels of carbon dioxide. An apnoea test confirmed absent respiratory drive. Ventilatory waveform graph analysis, revealed cardiogenic oscillation as the cause for autotrigerring.
Fast Solution for Solving the Modified Helmholtz Equation withthe Method of Fundamental Solutions
Authors: Chen C. S. , Jiang Xinrong , Chen Wen , Yao Guangming
Published: March 2015

The method of fundamentalsolutions (MFS)is known as aneffective boundary meshless method. However, the formulation of the MFS results in a dense and extremely ill-conditioned matrix. In this paper we investigate the MFS for solving large-scale problems for the nonhomogeneous modified Helmholtz equation. The key idea is to exploit the exponential decay of the fundamental solution of the modified Helmholtz equation, and consider a sparse or diagonal matrix instead of the original dense matrix. Hence, the homogeneous solution can be obtained efficiently and accurately. A standard two-step solution process which consists of evaluating the particular solution and the homogeneous solution is applied. Polyharmonic spline radial basis functions are employed to evaluate the particular solution. Five numerical examples in irregular domains and a large number of boundary collocation points are presented to show the simplicity and effectiveness of our approach for solving large-scale problems.

Диссипативное свойство кубического нелинейного уравнения Шрeдингера
Authors: Naumkin Pavel Ivanovich
Published: March 2015

Изучено поведение при больших значениях времени решений задачи Коши для нелинейного уравнения Шрeдингера. Рассмотрено взаимодействие резонансного члена с другими типами нелинейности. Доказано глобальное по времени существование решений и найдено их асимптотическое представление при больших значениях времени. Показано, что в дальней зоне убывание решений имеет тот же порядок, что и в линейном случае, в ближней зоне решения приобретают дополнительное логарифмическое убывание, которое оказывается
более медленным по сравнению со случаем, когда в уравнении Шрeдингера отсутствует резонансный член.

О положительной разрешимости некоторых классов нелинейных интегральных уравнений типа Гаммерштейна на полуоси и на всей прямой
Authors: Khachatryan Khachatur Aghavardovich
Published: March 2015

Исследованы некоторые классы нелинейных интегральных уравнений Гаммерштейна на полуоси и на всей прямой. Указанные классы уравнений возникают в теории переноса излучения в ядерных реакторах, в кинетической теории газов, в нелинейных конкуренционных системах Риккера для бегущих волн. Сочетание специальных итерационных методов с методами теории построения инвариантных конусных отрезков для соответствующего нелинейного оператора позволяет доказать конструктивные теоремы существования
положительных решений в различных функциональных пространствах. Приведены примеры, иллюстрирующие эти уравнения, для которых выполнены все условия сформулированных теорем.

Assess the Knowledge on Menopausal Self-care among Perimenopausal Women
Authors: Anjaly N , Philip T Anju
Published: March 2015

Perimenopause which generally begins more than 5 years before the permanent cessation of menses, it is a time of transition characterized by unstable endocrine physiology and highly variable, unpredictable hormone profiles. The purpose of the study is to assess the knowledge on menopausal self-care among perimenopausal women in selected wards of Nayarambalam Panchayath, Ernakulam. Quantitative approach with descriptive survey design is used for the study. Sample consists of 120 perimenopausal women of 35 to 50 years, residing in selected wards of Nayarambalam Panchayath, Ernakulam. The knowledge regarding menopausal self-care is poor among 71% of perimenopausal women, average among 28% of perimenopausal women and 1% of them have good knowledge. Mean knowledge score is 8.04, SD is 5.09 and maximum score is 30. No significant association was found between knowledge and variables like age, educational status, family income and menopausal status. Perimenopausal women have inadequate knowledge on menopausal self-care. Findings of the study highlight the need of educational intervention for improving the knowledge of self-care among perimenopausal women.

Authors: Agarwal Shelly , Gupta Samta , Chutani Nimmi , Gulati SS
Published: March 2015

Aims and objectives

To compare the efficacy of VIA and Pap smear for detection of premalignant and malignant lesions of cervix.

Materials and methods

Two hundred and forty women attending outpatient department of obstetrics and gynecology were subjected to detailed history taking, clinical examination, Pap smear and VIA, and biopsies were indicated.

Results

Of 240 patients, 27 patients (11.3%) were Pap positive and 28 patients (11.7%) were VIA positive. A total of 39 patients in whom either test was positive, had undergone cervical biopsy. Sensitivity of VIA and Pap smear was 92 and 84% respectively and specificity of VIA and Pap smear was 64.3 and 57% respectively.

Conclusion

The study concluded that sensitivity of VIA is comparable to Pap. Therefore, VIA is an efficacious and costeffective method to screen premalignant and malignant lesions of cervix, especially in developing countries like ours.

Authors: LNU Pushpalatha , Syamala O , LNU Rukshana , Sangeetha K , Rani G Usha
Published: March 2015

Objective

Vaginal reconstruction in Müllerian agenesis through nonsurgical method, using serial vaginal dilators which were worn by the patients with the help of a T-shaped perineal bandage.

Materials and methods

Seven patients with Müllerian agenesis had attended the outpatient clinic between 2008 and 2013. The age of women ranged from 18 to 30 years. This clinical report describes the use of prosthesis, fabricated by a maxillofacial prosthodontist that enabled the patients to have custom made personalized vaginal dilators of increasing dimensions which they could wear with comfort with a tight perineal T-bandage.

Results

Seven women with Müllerian agenesis had consented for nonsurgical mode of vaginal reconstruction. Vagina was serially dilated with tailor made prosthesis worn using tight perineal T-bandage for a period of 3 to 4 months. Post dilatation average vaginal length was 11 to 13 cm which allowed introduction of Sims speculum with ease.

Conclusion

Nonsurgical vaginal dilatation using prosthetic vaginal dilators kept in place with tight perineal T-bandage is a well-accepted custom made and a successful technique in the creation of neovagina.
