Authors: Mamcarz Piotr 
Published: February 2013

Abstract
The aim of the article is to present a very important phenomenon affecting human integrity and homeostasis that is Threat Prediction Process. This process can be defined as “experiencing apprehension concerning results of potential/ actual dangers,” (Mamcarz, 2015) oscillating in terminological area of anxiety, fear, stress, restlessness. Moreover, it highlights a cognitive process distinctive for listed phenomenon’s. The process accompanied with technological and organization changes increases number of health problems affecting many populations. Hard work conditions; changing life style; or many social and political threats have influence on people’s quality of life that are even greater and more dangerous than physical and psychological factors, which, in turn, have much more consequences for human normal functioning. The present article is based on chosen case studies of a qualitative analysis of threat prediction process
Genital Herpes / Genitalni herpes
Authors: Jovanović Marina 
Published: February 2013

Abstract
Genital herpes is a chronic, nearly always active herpes simplex virus (HSV) infection of sacral ganglia, that may appear bilaterally and in more ganglia than previously thought. It represents one of the most prevalent sexually transmitted infections, and the most frequent cause of genital ulcer disease in the general populations of developed countries. It is caused by HSV type-2 (HSV-2) in 60-80% of cases, with HSV-1 infections causing the remainder. Genital herpes caused by HSV-1 is on the rise. Since genital HSV-1 infections have higher risk for transmission from mother to infant during delivery than HSV-2, they account for 30% of all cases of neonatal herpes. Serological studies have found prevalence of HSV-2 in the general population of developed contries to be up to 25%. Thirty years ago, herpes was defined as “Today’s Scarlet Letter”in the absence of reliable serological tests and highly effective medications, for diagnosis and treatment of genital herpes. In 2000, apart from virus isolation in cell culture (70% sensitivity), that has long been regarded as the diagnostic gold standard, type specific serological tests and higly effective antiviral agents have evolved. However, the following questions were raised: should serological testing be routinely recommended in asymptomatic patients; can antiviral therapy reduce asymptomatic shedding of the virus; can antiviral therapy reduce sexual transmission of infection; can antiviral therapy reduce acquisitation of viral copathogens, such as human immunodeficiency virus (HIV)? Now, ten years later, we know the answers. Type specific HSV DNA detection by real-time PCR assays (100% sensitivity) are tests of choice for every person with recurrent genital ulcers lasting more than 4 days, and must be available in those laboratories currently performing a significant number of PCR tests for different purposes. Type specific IgG serology assays are indicated in all asymptomatic persons who are at increased risk for HSV infection. In sexually active patients experiencing ≥ 6 recurrences per year, daily supressive dose of acyclovir, valacyclovir or famciclovir should be discontinued after a maximum of a year of continuous antiviral therapy in order to reassess recurrence frequency. If necessary, the therapy should be restarted after at least two recurrences. With such expansive diagnostic possibilities and more aggressive therapeutic approaches, we can define genital herpes not as a “Scarlet Letter”, but as a “widespread untoward consequence of human sexuality”.
Multiple giant congenital nevi – a case report / Multipli gigantski kongenitalni nevusi – prikaz slučaja
Authors: Mikulić Vesna 
Published: February 2013

Abstract
Giant congenital melanocytic nevi are benign nevomelanocytic proliferations of 20 cm or more in diameter, present at birth. They are primarily found on the posterior trunk, but they may arise on any other part of the body, covering more than 2% of the body surface. Giant congenital nevi are major risk factors for the development of melanoma, and the risk has been estimated to be as high as 5-7%. Persons with giant congenital melanocytic nevi on the head, neck and along the midline of the back are at increased risk for leptomeningeal melanocytic lesions. Most patients with neurocutaneous melanosis present with neurologic manifestations of the disease in the first 2 years of life. Melanoma occurs in 62-80% of cases, but even without neoplasms, symptomatic neurocutaneous melanosis has a poor prognosis. This is a report of a 23-year-old female patient who presented with multiple congenital pigmented and pilous nevi covering over 2% of her total body surface, without malignant alterations or association with other abnormalities. At birth, a nevus covered her neck, shoulders and the upper left arm, whereas several nevi over 5cm in diameter were present in the gluteal region, on the abdomen and legs. During the first 2 years of life, the existing nevi increased in size and progressed into darker brown. New, smaller pigmented changes appeared on the whole body and the face, while at the age of 17 they reached their current size and layout. At puberty, nevi over 10cm in size grew dark hairs. There were neither melanoma nor skin tumor cases in the family. Nuclear magnetic resonance imaging was not performed in the childhood or later in life, but other parameters - neurologic and ophthalmologic findings were in normal range all the time, as was growth and development. A complete photo-documentation was made, including macroscopic and dermoscopic images and regular follow-ups continue. Giant congenital melanocytic nevi may cause considerable esthetic and psychosocial problems. Due to their high malignant potential, association with other abnormalities, no consensus on the treatment, and monitoring problems, giant congenital melanocytic nevi represent a therapeutic problem as well.
Lichen Planus in the Lines of Blaschko – A Case Report / Blaschko linearni lichen planus – prikaz slučaja

Published: February 2013

Abstract
Lichen planus is an acquired inflammatory disease of the skin, mucous membranes and nails. It is characterized by pruritic polygonal livid papules. The disease was first described by Erasmus Wilson in 1869. It is primarily a disease of adults, and it usually occurs between the ages of 30 and 60, without gender predominance. The exact incidence and prevalence of this disease are unknown, but it is thought to affect less than 1% of the general population (0.14 to 0.80%) (1).
A 63-year old male patient was admitted to our Department with itchy erythematous papules and plaques which appeared a month before admission. On admission, numerous erythematous and livid papules and plaques of polygonal shape up to 5 mm in diameter were present in the lines of Blaschko, along the left lower extremity, left side of the trunk and the left upper arm (Figures 1-3), while mucous membranes, nails and scalp were spared.
Blaschko-linear distribution of skin lesions was first described by a German dermatologist Alfred Blaschko in 1901 in his work ”The distribution of nerves in the skin and their relationship to diseases of the skin”. In 1978, Happle first published that genetic mosaicism was the cause of these peculiar skin changes (1,4,6). Although knowledge of mosaicism in the skin was further elucidated in articles of several authors (Taieb in 1994, Bolognia in 1994, Heide 1996), the exact mechanism and molecular basis for the development of Blashcko linear distribution has not been fully clarified yet (5). Blaschko lines may be related to X-linked, congenital and inflammatory dermatoses, and they may be found in several skin conditions like segmental forms of atopic dermatitis, erythema multiforme, pemphigus vulgaris, vitiligo, and granuloma annulare. This is a case report of a patient with a rare form of lichen planus, with typical clinical manifestations and with Blaschko-linear distribution. Lichen planus in the lines of Blaschko was also described in several other dermatoses: lichen striatus, lichen sclerosus, morphea, porokeratosis of Mibelli, mucinosis follicularis and psoriasis vulgaris. The treatment included topical corticosteroids under occlusion, due to comorbidities, with satisfactory response. Other options include, topical calcineurin inhibitors, intralesional and systemic corticosteroids, retinoids, phototherapy and in resistant cases that severely affect the quality of life methotrexate, cyclosporine and thalidomide.

Abstract
Myofibroblastic dermatofibroma (MFD) is an unusual neoplasm characterized by a predominance of myofibroblastic differentiation. It is extremely rare and it is not well described. Expressions of smooth muscle actin, CD34, S-100, desmin, CD31, and Factor XIIIa were evaluated along with hematoxylin-eosin and trichrome staining of fixed tissue specimens from a fibrohistiocytic neoplasm. The neoplasm demonstrated a storiform pattern characteristic of fibrohistiocytic origin. It was strongly and diffusely positive for smooth muscle actin and vimentin, and negative for all other stains performed. A trichrome stain showed the entire tumor to be blue, demonstrating the collagenous and fibrous tissue to a marked degree. MFD is a distinct variant of dermatofibroma characterized by a predominance of myofibroblastic differentiation.
A Triad of Exophtalmos, Pretibial Myxedema and Acropachy in a Patient With Graves’ Disease / Egzoftalmus, pretibijalni miksedem i akropatija − trijada prisutna kod obolelog od Grejsove bolesti

Abstract
A classical triad of extrathyroidal manifestations of Graves’ disease known as EMO syndrome (exophthalmos, pretibial myxedema and osteoarthropathy) is a rare condition. This paper presents a 39-year old male patient who underwent chemo- and radiation therapy of the supradiaphragmatic area due to Hodgkin’s disease at the age of 35 and 36 leading to remission. Two years later, the patient developed general symptoms of Graves’ disease and ophthalmopathy, with high thyroid stimulating hormone levels. Four months later, the patient presented with pretibial myxedema. Thirteen months after the onset of the disease, higher levels of thyroxine and decreased levels of thyroid stimulating hormone were registered. The diagnosis of EMO syndrome was confirmed by radiologic and histopathological analyses. Thiamazole and intralesional corticosteroid therapy were administered, resulting in euthyreosis and decrease of pretibial myxedema. The question is whether the autoimmune thyroid disease was triggered by the previous disease, or by chemo- and radiation therapy..
New Reconstruction Technologies Of Safety Pillar In Mines / Nowoczesne Technologie Odbudowy Filara Bezpieczeństwa w Kopalniach
Authors: Gonet Andrzej , Stryczek Stanisław , Brudnik Krzysztof 
Published: February 2013

Abstract
Safety pillars are made around mines as a protection measure. This is especially important in salt mines where the surrounding waters are most hazardous. Without maintaining safe conditions the mine may be water-flooded as it was the case in one of the Polish mine “Wapno“. An original technology linking pipeline injection and hole injection methods has been used for the reconstruction of a safety pillar in the Salt Mine “Wieliczka“. This solution turned out to be successful when on 13 April 1992 the mine was saved from flooding after a disastrous water flux to the transverse working Mina. The presented technology can be efficiently used in various mines at the stage of designing, though their exploitation to the closing stage.

Abstract
The paper addresses the problem of the forecasting and possible development of gas production from unconventional plays in Poland. As authors underline the potential of Polish shale gas is quite similar to US shales. Due to geological conditions, stage of development, size and location in more urban areas some experts compare Polish shale plays to Marcellus even. Document stated that from geographical and infrastructural points of view one can identify five different directions for export of natural gas surplus from Poland. It is important to notice that currently none of those routes physically exists - it means, that at present there are no infrastructure (or access to such infrastructure) for exporting of the Polish natural gas.

Published: February 2013

Abstract
This paper discusses issues involved in protecting buildings and utilities infrastructure located on areas affected by mining exploration. They have been presented against the backdrop of current situation and growth perspectives for Polish mining.
Characteristics of Polish mineral deposits have been determined and the scale of mining-induced impact has been given as an aggregate mining areas and regions. Current situation and growth perspectives have been evaluated through analysing geological concessions granted by Ministry of the Environment.
The nature of mining influences induced by underground coal - black coal being the most intensively explored mineral in the country - mining has been discussed. Building protection issues have also been presented from three angles: forecasting of mining influences, designing protections and structural health monitoring.

Static and dynamic analyses of the stability of mining wastes (Ravaneti) in the Carrara marble area (Apuan Alps, Italy) / Analiza statyczna i dynamiczna stabilności hałd odpadów górniczych w regionie wydobycia marmurów Carrara (Alpy Apuańskie, Italia)
Authors: Oreste Pierpaolo , Soldano Silvia 
Published: February 2013

Abstract
The problem of the stability of “ravanetos” (debris piles of mining waste material extracted from the Apuan Alps, Italy) is very relevant, because of the consequences a landslide would have on the people and the existing civil infrastructures throughout the territory.
In this work, the stability of two ravanetos that can be considered as representative of those in the Carrara area has been studied: the Polvaccio ravaneto, a recent type of debris pile and the Torrione-Tecchione, an old debris pile at present undergoing re-naturalisation.
The study using the LEM (Limit Equilibrium Method) in a static and pseudo-static field, has made it possible to first carry out a back-analysis to define the most probable apparent cohesion and friction angle values of the material that makes up the ravanetos. Subsequently, it was possible to determine the intensity of the seismic wave that would be able to lead the two ravanetos to limit stability conditions and to determine the probability of such a seismic wave occurring in the next 50 years.
A more accurate analysis, carried out with a numerical method in the dynamic field, of the most critical condition (the Polvaccio ravaneto) has led to more conservative results (higher safety factors) than those obtained with the LEM. This result allows us to reveal how the LEM can be considered a cautionary instrument to judge the stability of debris piles during a seismic event and that the likelihood of a landslide occurring in the two studied representative ravanetos over the next 50 years is very slim.
The Influence of Operating Loads on the State of Stress and Strain in Selected Load-Bearing Elements of a Tower-Type Headgear Structure in the Light of the Experimental Data / Wpływ Obciążeń Eksploatacyjnych Na Stan Naprężenia Oraz Przemieszczenia Elementów Nośnych Konstrukcji Basztowej Wieży Szybowej W Świetle Przeprowadzonych Eksperymentów
Authors: Wolny Stanisław 
Published: February 2013

Abstract
In order that the ultimate state method should be applied to the strength analysis of the tower-type headgear structure, it is required that the design loads and endurance parameters be first established. For that purpose the characteristics of loads experienced by structural elements of the headgear structure are required (Wolny, 2012) as well as the numerical analysis of stresses and strains. Thus obtained results are verified through stress (strain) measurements taken in structural elements subjected to highest loads found on the basis of the stress map derived from numerical analysis, being the subject matter of the present study.
Strain (stress) measurements are taken on the beams located at the floor level +65.00 m on which the winding machines are positioned (drive shaft bearings, stators in the electric motors), as shown schematically in Fig. 2.
The strength analysis by numerical methods is restricted to those elements of the load bearing structure in the headgear at the level (+65.00) where the strain (stress) and measurements are taken and where loads are measured that give rise to the maximal strain changes (Wolny, 2012).
Alongside the strain (stress) measurements in the load-bearing elements of the headgear structure, measurements are taken of horizontal displacements at selected points of the structure with the use of an interferometric radar IBIS-S.
Results of the repeated numerical analysis of the state of stress, restricted to those elements of the load bearing structure in the tower-type headgear where the maximal loads are registered (Wolny, 2010), agree well with experimental data obtained from tests done on a real object. Therefore, the numerical analyses of the state of stress and strain in the load-bearing elements of the headgear structures operated in the Polish collieries lead us to the assumption that when analysing the geometry of the driving systems in the winding gear, the structures on which the elements of the winder installation are positioned ought to be treated as rigid. This conclusion is further corroborated by displacement measurements by geodetic methods taken on selected points of the tower-type headgear structure. An interesting point is that the tower-type headgear structure above its first floor level will behave as a rigid solid.
The Effect of Different Delivery Conditions on the Accelerated Degradation of Structural Steel in the Coal Mine Environment / Wpływ Różnego Stanu Dostawy Na Przyspieszoną Degradację Stali Konstrukcyjnej W Środowisku Kopalnianym
Authors: Pawłowski Bogdan , Bała Piotr 
Published: February 2013

Abstract
The main objective of this work was to determine the effect of different delivery conditions on the accelerated degradation of structural steels used for lifting beams (rails) of the monorail transport systems. Some of these rails, made of the same steel grade as others, undergoes accelerated corrosion in the coal mine environment. Corrosion degradation occurs much faster (more than two times faster), comparing to the same steel grade rails operated under the same conditions but with different microstructures. However, all the provided rails meet the requirements of appropriate standards for steel on the lifting beams of the monorail transport systems.
The investigations were carried out on rails made of the same steel grade but with different microstructures and showed that the main factor influencing the accelerated corrosion degradation of tested steels is the delivery condition, so-called “as rolled” condition. The greatest resistance to the accelerated corrosion showed rails in the normalized or normalizing rolling condition.

Abstract
The main subject of this paper focuses on scientific and research activities conducted in the Institute of Mining Engineering and Safety of the VŠB-Technical University of Ostrava. Cooperation between the VŠB-Technical University of Ostrava and OKD A.S., the only representative of coal mining in the Ostrava-Karviná coal basin, has recently begun to develop again. This paper describes an example discussed in a certain study, which has been undertaken for the Paskov mine, OKD a.s., dealing specifically with the evolution of microclimate parameters in mines that depend on the progress of mining activity at deeper levels over a period of several years. To this end, a special program, aimed at determination of the necessary refrigerating capacity, was established at the VŠB-Technical University of Ostrava.
Charakterystyka mineralogiczno-chemiczna i teksturalna odpadów poflotacyjnych z przemysłu Zn-Pb pod kątem dalszych rozważań wykorzystania ich jako sorbentów
Authors: Wdowin Magdalena , Gruszecka Agnieszka 
Published: February 2013

Streszczenie
Celem pracy była wstępna charakterystyka (mineralogiczna, chemiczna, teksturalna) odpadów poflota­cyjnych, stanowiących surowiec uboczny (odpadowy) przy uzyskiwaniu koncentratów cynkowo-ołowiowych, pod kątem dalszych analiz nad możliwością ich perspektywicznego (eksperymentalnego) wykorzystania jako sorbentów gazów kwaśnych (SO2 iCO2). Składowisko tych odpadów jest własnością ZGH „Bolesław" w Bukownie. Materiał badawczy stanowiła próbka odpadów poflotacyjnych pobrana ze stawu osadowego nr 1, leżącego w południowej części Stawu Zachodniego. Charakterystyka wytypowanych do badań materiałów obej­mowała podstawowe badania mineralogiczne (XRD, SEM-EDS), analizy chemiczne (oznaczenie zawartości wilgoci analitycznej, zawartości strat prażenia, podstawowego składu chemicznego, jak też pierwiastków śla­dowych) oraz wyznaczenie podstawowych parametrów teksturalnych (powierzchnia właściwa BET, rozkład i wielkość porów). Badania mineralogiczne wykazały, że materiał odpadowy stanowią głównie minerały węg­lanowe (w przewadze kalcyt, dolomit, ankeryt) oraz minerały stanowiące pozostałość po niewyflotowanych kruszcach (w przewadze galena, sfaleryt). Analiza chemiczna pozwoliła stwierdzić, iż w analizowanej próbce dominują związki wapnia, magnezu i żelaza uwarunkowane przewagą minerałów węglanowych w badanych odpadach. Wśród pierwiastków śladowych przeważa arsen, następnie mangan i bar, występujące jednak w ilości nie przekraczającej 1%. Analiza teksturalna wykazała, że materiał badawczy charakteryzuje się niską po­wierzchnią właściwą i dużymi rozmiarami cząstek. Przeprowadzone badania sugerują, że analizowany materiał charakteryzuje się ubogimi właściwościami adsorpcyjnymi, aczkolwiek mógłby on znaleźć zastosowanie w metodach odsiarczania, jak też neutralizacji dwutlenku węgla (karbonizacja). Należałoby jednak w tym celu przeprowadzić dodatkowe badania wymywalności metali ciężkich w środowisku kwasowym, jak też zastosować domieszki innych składników, takich jak cement czy zeolity, w celu immobilizacji niebezpiecznych składników odpadów.
