Opis:
Free gas in the peritoneal cavity is not always associated with gastrointestinal perforation. The study presented a case of a 72-year old male patient with peritoneal emphysema, which developed after ventilation therapy. Suspecting gastrointestinal perforation the patient was subjected to laparotomy, which did not show perforation. The patient was diagnosed with spontaneous pneumoperitoneum. The patient died, due to cardiopulmonary and neurological disturbances. Withdrawal from non-therapeutic laparotomy may prove crucial in similar cases.

Opis:
The article is a summary of information about evaluation of a risk degree for a brown coal spontaneous ignition which is realized on the base of a database analysis of information about the development of stative quantities and desorbated gases in the stored bodies of the brown coal. The data were gained from the long term complex measurements which were realized at chosen companies during the coal mining in the previous parts of the project. In the last part of the project, we examined results of temperature models from thermographs with results of gasses and coal samples from the mines. Then, the influence of atmospheric conditions (insolation, water downfall, changes of barometric pressure etc.), the influence of coal mass degradation, the influence of physical and chemical factors, and the influence of other defective factors on the process of the coal spontaneous ignition. The gasmetry was assess with gas in-situ samples and laboratory gas models of indicative gasses for the spontaneous ignition, which were taken from the method of the ther-mic oxidation with the aim of the correlation finding for an epicentre of temperature within the spontaneous ignition.

Opis:
Spontaneous, idiopathic urinary bladder rupture is a very rare disease entity, which may face the problem of proper preoperative diagnosis. In many cases the medical history, physical examination, and additional tests raise false suspicion of gastrointestinal perforation. The study presented a case of a female patient with spontaneous urinary bladder perforation, paying particular attention to the diagnostic difficulties associated with the above-mentioned pathology. The aim of the study was to analyse the presence of symptoms and imaging and laboratory results observed in case of spontaneous urinary bladder rupture, as well as differentiate the above-mentioned pathology with gastrointestinal perforation. Whenever diagnosing a patient with acute peritonitis symptoms, in whom the predominating symptoms include sudden abdominal pain, peritoneal cavity fluid presence, hematuria, oliguria, and coexisting increased urea, creatinine, and potassium levels, one should consider the possibility of urinary bladder rupture.

Language functions, particularly disordered lexical skills were diagnosed in the examined woman based on selected diagnostic tests of the Boston Diagnostic Aphasia Examination (BDAE). Furthermore, an experimental version of the author's original test for assessing lexical-semantic performance in dementia was used. The author presents a case study of a 79-year-old woman diagnosed with logopenic variant primary progressive aphasia (lvPPA) secondary to Alzheimer’s disease. The author describes the symptoms of anomie manifested by the study participant and the supplementary strategies she applied in the case of lexical deficits. The analysis of the findings obtained in the course of language function assessment allowed the author to assess the fluency of speech, speech comprehension, repetition and naming. The study participant diagnosed with lvPPA was observed to manifest the following: an absence of motor speech disorders, absence of characteristics of evident agrammatism, preserved comprehension of individual words, preserved semantic knowledge of objects, disordered retrieval of words in spontaneous speech and in attempts to name, and disordered repetition of sentences and phrases. The analysis of the discussed case study allowed the author to discuss the progressive lexical deficits manifested by the lvPPA patient and to record those supplementary strategies that were most frequently applied in the lexical difficulties experienced by the female patient diagnosed with lvPPA.

Opis:
Primary spontaneous pneumothorax could be a serious therapeutic problem in case of recurrence. Lack of therapeutic standards sometimes leads to delay in definitive surgical treatment and could cause respiratory complications. The aim of the studywas the evaluation of treatment results in patients with recurrence of primary spontaneous pneumothorax and looking for optimal therapeutic method after first recurrence (surgical treatment vs. pleural drainage). Material and methods.Between 01.01.2009 and 31.07.2010 fifty four patients with recurrent primary spontaneous pneumothorax was hospitalized in Wrocław Thoracic Surgery Centre (24.3% of all patients with pneumothorax). The recurrence was treated surgically in 24 cases, in 30 pleural drainage was performed: simple drainage (n=14) or drainage with chemical pleurodesis (n=16). Mean age of patients treated without surgery was higher than surgically treated (p=0,012). Results.In surgery group no recurrence was found, in drainage group 11 recurrences occurred (p=0.0009). In group of 11 patients with second recurrence, pleurodesis was performed four times (36%) vs. 12 times (63%) in 19 patients without a recurrence of the disease. 70% of non-surgically treated patients vs. 50% of surgically treated were afraid of recurrence (p=0.01). Among 11 patients in drainage group, nine underwent surgery at the second episode of recurrence. Conclusions.The optimal treatment method in case of first recurrence of primary spontaneous pneumothorax is surgical treatment. When it is not possible chemical pleurodesis should be performed during pleural drainage. Most of the patients after second recurrence are treated surgically anyway. The surgical treatment significantly reduces patient’s fears for future recurrence of the disease. Younger patients are most often surgically treated.

Opis:
The liability of coal to spontaneous combustion is the principal cause of mine fires. Spontaneous combustion is one of the main threats in Polish and Vietnamese coal mines. The article presents an analysis of the spontaneous combustion of coal in mines of both countries. It is related to the natural prone of coal to spontaneous heating and consequently to its self-ignition. Despite the relevant recognition of the methods of preventing this threat, in mines, spontaneous combustion occurs during the exploitation of coal seams with low and very high self-ignition tendency. Apart from the technical factors related to the design of coal seam mining, the properties of coal have a significant impact on the occurrence of spontaneous combustion. Their correct recognition is essential to the precautions against spontaneous combustion for minimalizing the risk of a mine fire. Therefore, it is necessary to study the factors influencing the propensity of coal to spontaneous heating. A review of the methods used to determine the propensity of coal to spontaneous combustion is presented in the article. Based on the high-temperature method of determining the propensity of coals to spontaneous combustion, the influence of selected factors related to samples' preparation for testing on the determination result was investigated. The influence of the fractional decomposition and the moisture content in the prepared samples on the determination result was demonstrated. The presented research results may improve research procedures for determining the propensity of coal to spontaneous combustion.

Introduction: Spontaneous Cholecystocutaneous Fistula occurs as a result of complication from untreated gall bladder stone disease infrequently seen in surgical practice due to early diagnosis of gall stone disease with imaging and appropriate and prompt antibiotic and surgical treatment. Case report: We report our experience with a 40-year-old woman who presented with a yellowish discharge from the umbilicus. Abdominal examination revealed a sinus opening at the umbilicus with the yellowish discharge and a vague mass in the right hypochondrium. CT fistulogram showed tract extending form the umbilicus to the gall bladder. Open cholecystectomy with excision of the fistulous tract was carried out. Histopathological examination showed chronic inflammation of the gall bladder with the fistulous tract lined by inflammatory granulation tissue. Post-operative recovery was normal and uneventful. The patient was normal in follow-up. Cholecystocutaneous fistula is a rare clinical entity. The diagnosis is established with CT and MRCP. Surgery remains the mainstay of treatment.

Background: Anticoagulants are used mainly in the prevention of venous thromboembolism. The frequency of haemorrhagic complications is correlated with patients’ age and level of International Normalized Ratio (INR). Spontaneous intramedullary spinal cord haemorrhage due to anticoagulation therapy is an extremely rare occurrence. A 62-year old male was admitted to hospital with acute abdominal pain and paraplegia. Because of persistent atrial fibrillation and previous history of ischaemic stroke, on admission the patient was treated with anticoagulant, INR – 15. MRI revealed an abnormal fusiform hyperintesity area in the spinal cord. ‘Haemo’ sequence confirmed the presence of hemosiderin deposits at the level of Th5 – Th7. Anticoagulation therapy might be a cause of spontaneous intramedullary spinal cord haemorrhage. Maintaining high levels of clinical suspicion and utilizing MRI with additional ‘haemo’ option may help in making the right diagnosis.

Opis:
The article follows the research of the project number TA01020351 called “The research of possibilities when predicting steam origin and consequent spontaneous ignition of brown coal fuels” which was researched with the support of the Technological Agency in the Czech Republic in 2011-2014 in the connection with a realized technical research. Therefore, it gives a summary information about the evaluation of the risk degree for the origin of spontaneous ignitions of the brown coal. The presented way of evaluation is based on a numeric expression of a value for MHU criteria – the point load of particular indicators is added together with other results gained from this research project. Then, more information is taken from companies running the dumps of brown coal products – both for suppliers (mining companies) and big consumers (power engineering). The complex knowledge about prediction of the origin of the spontaneous ignition enables to make an early response to eliminate a threat of mining fire in open pit mines or on the dumps of coal products. Consequently, it reduces the risk of fire and breakdowns of transportation means DPD, heavy machines and preparation plants. The working injuries are reduced as well – burns by coal in fire or inhalation of gas products from imperfect combustion.
Treścią tego artykułu są wyniki badań zrealizowane w ramach projektu TA01020351 pt: „Badania możliwości przewidywania i konsekwencji samozapłonu węgla brunatnego“ które zostały przeprowadzone przy wsparciu Agencji Techniki w Republice Czeskiej w latach 2011-2014, w połączeniu z badaniami technicznymi. W wyniku tych badań uzyskano informacje dotyczące oceny stopnia ryzyka powstania samozapłonu węgla brunatnego. Przedstawiony sposób oceny jest oparty na metodzie numerycznej wyrażania wartości dla kryteriów MHU – wartości poszczególnych wskaźników są sumowane z innymi wynikami uzyskanymi w trakcie realizacji tego projektu badawczego. Uwzględniono również informacje pochodzące od firm działających na hałdach węgla brunatnego – zarówno od dostawców (firm górniczych) jak i dużych odbiorców (energetycznych). Kompleksowa wiedza o przewidywaniu samozapalenia węgla brunatnego umożliwi wyeliminowanie zagrożenia pożarem w kopalniach odkrywkowych oraz na hałdach. W konsekwencji zmniejszy się ryzyko pożaru, awarii środków transportu DPD, ciężkich maszyn i w zakładach przeróbczych. Zredukowane zostaną obrażenia pracowników, a także oparzenia wywołane przez pożar węgla brunatnego lub wdychania produktów gazowych z procesu niedoskonałego spalania.

Opis:
W artykule przedstawiono metodę oznaczania skłonności węgla do samozapalenia, gdzie temperatura rozpoczęcia procesu samozagrzewania odpowiada temperaturze otoczenia (skał). Problemem w tym przypadku, na który szczególnie zwrócono uwagę, jest to, że w warunkach zalegania pokładu węgla temperatura otoczenia jest zmienna. W pierwszej części artykułu przeanalizowano jak wpływa na proces samozagrzewania temperatura rozpoczęcia tego procesu i jego zakończenia. W oparciu o to ustalono, dla jakiego przedziału temperatury będzie sformułowany wskaźnik samozapalności. Następnie wyprowadzono metodę oznaczania skłonności węgla do samozapalenia, która jest zależnością funkcyjną f: T → SMP przyporządkowującą dwa zbiory, temperaturę rozpoczęcia procesu samozagrzania T i wskaźnik samozapalności SMP. Istotą uzyskanej funkcji jest całka oznaczona wyprowadzona z równania różniczkowego opartego o równanie Arrheniusa, która określa czas, po jakim w warunkach adiabatycznych następuje przejście układu od temperatury rozpoczęcia procesu samozagrzewania T0 do temperatury zapłonu Tz. Wskaźnik samozapalności dla zmiennej temperatury początkowej SMP(T= T0) został wyprowadzony w zakresie temperatury T0 = 295 do 325 ºK (22 do 52ºC). W końcowej części artykułu omówiono sposób podziału grupowego, który uwzględnia zmienną skłonność węgla do samozapalenia w zakresie temperatury T0 = 295 do 325 ºK (22 do 52ºC). Przedstawiono w jaki sposób ustalono 5-grupowy podział skłonności węgla do samozapalenia. Pokazano również, na przykładzie 953-elementowej próby węgli jak zmienia się skłonność do samozapalenia wraz ze zmianą temperatury początkowej samozagrzewania.
The article presents a method for determining the propensity of coal to spontaneous combustion, in which the start temperature of the self-heating process correspond to the ambient temperature (rocks). The problem in this case, which is particularly noteworthy, is that in the conditions of depositing the coal seam, the ambient temperature is variable. In the first part of the article it was analyzed how the temperature of the start of this process and its ending affects the self-heating process. On the basis of this, it was determined for which temperature range the self-ignition index will be formulated. Next, a method for determining the propensity of coal for spontaneous ignition was derived, which is a functional relationship f: T → SMP assigning two sets, the start temperature of the self-heating process T and the SMP self-ignition index. The essence of the obtained function is the definite integral derived from the differential equation based on the Arrhenius equation, which determines the time after which, in adiabatic conditions, the system passes from the start temperature of the self-heating process T0 to the ignition temperature Tz. The spontaneous combustion index for variable initial temperature SMP(T= T0) was derived in the temperature range T0 = 295 to 325 ºK (22 to 52ºC). In the final part of the article it was discussed the group division method, which takes into account the variable propensity of coal to self-ignition in the temperature range T0 = 295 to 325 ºK (22 to 52ºC). It was presented how the 5-group of coal propensity distribution for self-ignition was established. It was also shown, on the example of 953 elements of coal samples, how the propensity to spontaneous combustion changes with the change of the initial temperature of self-heating.

Opis:
Spoil tips are anthropomorphic terrain structures built out of leftover materials from underground or open pit mining. Usually the term spoil tips refers to those build out of unusable particles from coal exploration. As such they consist mostly of slate and various types of sandstone or mudstone. But also include some amount of coal and, what is more important, coal dust. Fires of spoil tips are dangerous to the environment and humans. They can cause degradation of air, and water qualities. Sometimes degradation to the environment can be irreversible. The presented survey was done in two stages. the first included creating a general terrain model. This was done with the use of long range laser scanner. The second step was a more detailed analysis of spatial and temperature conditions. Two measuring seasons ware performed. The first included a survey made with a short range laser scanner and a hand-held inferred camera. The obtained point cloud was supplemented with temperature value with the use of software and hardware provided by the authors. The visualization of 3D discreet thermal model was done in Bentley MicrioStation. The second included a usage of Z+F IMAGER 5010 laser scanner equipped with T-Cam Rev 1.0 thermal camera insole. A new and unique device that connects laser scanner with infrared camera. This season also provide a point cloud with attached temperature value of measured points. This article provides the description of those two methods including a comparison of their effectiveness and costs. It also describes the heat conditions occurring on spoil tip of Lubelski Węgiel „Bogdanka” S.A coal mine surveyed in December 2015.

It was shown that vegetation identified on the waste dump is similar to the plants growing around this area. What is more, ecological succession of Urticaceae was observed, which proves succession of plants preferring alkaline soils. In addition, the ecotoxicological tests did not show the contamination impact of soil samples. We recorded only a slight inhibition of growth of A. sativa (in the shoot length in lower part of dump).

The current article explores the potential innovativeness of Involuntary Musical Imagery and presents the current state of InMI researches. There is a lack of precise definition of the term, as well as related terms (such as earworm or musical imagery). InMI is often equated to earworms which does not do justice to its creative potential. Several authors suggest that InMI can be a source of new melodies useful for composers in their composition process. The article proposes that InMI can consist of new melodies and appear as a single event. Composers use their working memory and musical abilities to volitionaly loop the tune in their head, then transcribe it into external realm (notation, recording). Composers can later use it in their creative process. The use of InMI in composing is a matter of individual differences between composers.

Introduction: This study compares physical activity of children in a state kindergarten and a forest kindergarten, particularly the number of steps taken, which can indicate the quantity of physical activity. The objective is to monitor the number of steps taken by children in selected institutions and to conduct an analysis in relation to the structure of the daily programme and movement regimen of these institutions contributing thus to the discussion concerning physical literacy formation among preschool children. Methods: The study is of a descriptive non-intervention character using mechanical pedometers. The sample consists of 73 children (36 in the state kindergarten, 37 in the forest kindergarten). The data are processed using a nonparametric Mann-Whitney test and Cohen's d. Results: At the significance level of 0.05 it was discovered that children from the forest kindergarten take significantly more steps in the observed period than children from the state kindergarten. The Zscore is -4.357 and p < 0.001. Substantive significance for the level of physical activity measured by the number of steps is high. Cohen's d = (532057-354714)/133355.005729 = 1.33. Conclusion: Physical literacy is influenced by both the quality of physical activity and the quantity, which was larger in the forest kindergarten. This may be related to the amount of spontaneous physical activity and the frequency and length of trips. However, controlled physical activities in the state kindergarten, especially morning exercise, can improve the quality and increase physical literacy as well. There is a need for a competent approach of teachers, sensitive inclusion of physical activities in the daily programme with emphasis on internal motivation, and awareness of benefits and drawback of both spontaneous physical activity and controlled activities represented by regular morning exercise.
