Opis:
Wraz z wyczerpywaniem się aktualnie eksploatowanych złóż gazu ziemnego znajdujących się w zachodniej Syberii czy części europejskiej Rosji (region Powołża), zwiększyło się znaczenie złóż położonych na Półwyspie Jamalskim, położonym za północnym kołem podbiegunowym i będących swoistym przedłużeniem pasma górskiego Uralu, a także miejscem ujścia rzeki Ob do Morza Karskiego. Wydobycie gazu ziemnego na Półwyspie Jamalskim (Jamał w języku Nieńcow - rdzennych mieszkańców Półwyspu - oznacza koniec świata) jest realizowane z 11 złóż gazu ziemnego (oraz ropy naftowej - z 15 złóż), z których najważniejsze to: Bowanienkowskoje, Charasa-wejskoje, Nowoportowskoje, Jużnotambiejskoje, Siewierotambiejskoje i Zapadnotambiejskoje, odkrytych jeszcze w latach 70. XX w.

Opis:
Introduction. Leukoplakia and oral lichen planus (OLP) are common diseases manifesting as white lesions that are considered potentially malignant disorders (PMD). Epithelial dysplasia may be an early sign of potency for the future transformation into oral squamous cell carcinoma (OSCC). A routine biopsy and close observation are recommended for persistent white oral lesions. As frictional keratosis may mimic oral leukoplakia, the question arises:Is there a need for a biopsy of persistent white lesion of traumatic origin? Materials and methods. Data from 643 oral tissue biopsies were retrospectively analyzed. A total of 176 (27.37%) results with provisional diagnosis of leukoplakia (36 cases), OLP (77 cases) and frictional keratosis (63 cases) were selected. Retrospective data collected included age, gender, smoking status, provisional and histopathological diagnosis. The data was analyzed to assess the prevalence of epithelial dysplasia and OSCC in terms of age, gender and smoking status. Results. Five (2.84%) cases of OSSC were reported, all of them were graded as G1; four cases of OSCC were found in clinically defined leukoplakia lesions; one case of OSCC (1.3%) was found in OLP biopsy; epithelial dysplasia was reported in 5 lesions (2.84%) provisionally diagnosed as OLP (3 cases), and leukoplakia in 2 cases. No dysplasia or OSCC were found in the lesions diagnosed as frictional keratosis. Conclusions. Epithelial dysplasia and OSCC may be found in leukoplakia or OLP lesions not initially suspected of any malignancy. In some cases, clinical features are not sufficient to diagnose a lesion without histopathology. Frictional keratosis is easily identified by clinicians, and may not require a biopsy in every case. Clinical and histopathological evaluation of the white lesions still needs improvement.

Opis:
In this paper, the Maximal Size Matching with Permanent Selection (MSMPS) scheduling algorithm and its performance evaluation, under different traffic models, are described. In this article, computer simulation results under nonuniformly, diagonally and lin-diagonally distributed traffic models are presented. The simulations was performed for different switch sizes: 4×4, 8×8 and 16×16. Results for MSMPS algorithm and for other algorithms well known in the literature are discussed. All results are presented for 16×16 switch size but simulation results are representative for other switch sizes. Mean Time Delay and efficiency were compared and considered. It is shown that our algorithm achieve similar performance results like another algorithms, but it does not need any additional calculations. This information causes that MSMPS algorithm can be easily implemented in hardware.

Opis:
In this paper the new packet switch architecture with multiple output queuing (MOQ) is proposed. In this architecture the nonblocking switch fabric, which has the capacity of N _N2 N2, and output buffers arranged into N separate queues for each output, are applied. Each of N queues in one output port stores packets directed to this output only from one input. Both switch fabric and buffers can operate at the same speed as input and output ports. This solution does not need any speedup in the switch fabric as well as arbitration logic for taking decisions which packets from inputs will be transferred to outputs. Two possible switch fabric structures are considered: the centralized structure with the switch fabric located on one or several separate boards, and distributed structure with the switch fabric distributed over line cards. Buffer arrangements as separate queues with independent write pointers or as a memory bank with one pointer are also discussed. The mean cell delay and cell loss probability as performance measures for the proposed switch architecture are evaluated and compared with performance of OQ architecture and VOQ architecture. The hardware complexity of OQ, VOQ and presented MOQ are also compared. We conclude that hardware complexity of proposed switch is very similar to VOQ switch but its performance is comparable to OQ switch.

Opis:
Purpose: To assess the physical and psychosocial situation and needs of Polish patients with Hodgkin lymphoma (HL), who had undergone radical chemoradiotherapy.Materials and methods: 50 Hodgkin lymphoma patients were asked to complete an institution-developed questionnaire concerning their physical, emotional and social well-being, as well as their perceptions regarding the medical care they had received. Results:The physical and psychosocial quality of life of patients with HL was diminished by the disease and its treatment. The most frequently reported side effects of both chemo- and radiotherapy were fatigue and loss of taste. The observed symptoms were slight or moderate. Although 36% of participants reported feelings of depression and 52% - were concerned about their future functioning in society, more than half of patients reported that were happy (60%). 20% of respondents were unable to work at all, but more than half had some difficulties with their employment. 20-40% of the patients complained about having received insufficient dietary instructions and lack of information about the late adverse effects of treatment. Although the majority of respondents assessed the quality of medical care as very high emotional problems preferred to share with relatives (90%).Conclusions:Although the physical and psychosocial situation of HL patients may be affected by the disease and its treatment, for the majority of patients, these impediments did not cause serious deterioration in functioning. Medical care was positively assessed by the HL patients, but more emotional and informative support is needed to decrease patients’ anxiety regarding future functioning in society.
