Opis:
The paper presents application of differential electronic nose in the dynamic (on-line) volatile measurement. First we compare the classical nose employing only one sensor array and its extension in the differential form containing two sensor arrays working in differential mode. We show that differential nose performs better at changing environmental conditions, especially the temperature, and well performs in the dynamic mode of operation. We show its application in recognition of different brands of tobacco.

Opis:
Detection and identification of toxic environmental gases have assumed paramount importance precisely in the defense, industrial and civilian security sector. Numerous methods have been developed for the sensing of toxic gases in the environment ever since surface acoustic wave (SAW) technology came into existence. Such SAW sensors called electronic nose (E-Nose) sensor use the frequency response of a delay line/resonator. SAW device is focused and given importance. The selective coating between input and output interdigital transducers (IDTs) in the SAW device is responsible for corresponding changes in operating frequency of the device for a specific gas/vapour absorbed from the environment. A suitable combination of well-designed SAW delay lines with selective coatings not only help to improve sensor sensitivity and selectivity but also leads to the minimization of false frequency alarms in the E-Nose sensor. This article presents a comprehensive review of design, development, simulation and modelling of a SAW sensor for potential sensing of toxic environmental gases.

Opis:
The article presents a perspective of somatic present in the prose of Nikolai Gogol. The body is treated here as a project — a collection of body fragments. Particular attention is paid to the figure of nose, which occurs in two selected short stories entitledNose and Diary of a Madman. Therefore, any attempt to emancipate the body part is a threat to the need to preserve the face. Nose is a sense of belonging. This part of the body is thus a limit to what we used to be referred to as belonging to us. Its location creates the last bastion of perception, the selfness.

Objective: The aim of this study was to evaluate cases of of ear, nose and pharyngeal (ENT) foreign body (FB) in pediatric patients referred to the pediatric emergency department of the Department of Otorhinolaryngology in Tokat State Hospital (Turkey). Methods: The paper comprises a retrospective study of all ENT foreign bodies presented to the pediatric emergency Department of Otorhinolaryngology in Tokat State Hospital (Turkey) between January 1, 2012 and December 31, 2018. Subject to evaluation were also demographic and clinical characteristics of the patients, types and anatomic locations of FBs, locations of FB by age groups, the method used to remove FBs and the distribution of FB cases by months. Results: A total of 829 FB cases were evaluated in this study. The mean age of patients was 47.8 ± 31.4 months. Of all patients, 404 (48.5%) were male, and 425 (51.2%) were female. The nose (58.7%) and the ear (20.2%) were the most common anatomical locations followed by mouth/pharynx/tonsil (12.3%), esophagus (6.2%) and the laryngotracheobronchial tree (2.4%). The most common FBs in different locations were beads in the nose (30.8%), beads in the ear (32.1%), fishbones in the mouth/pharynx/tonsil (56.8%), nuts and peanuts in laryngotracheobronchial tree (70%) and a coin/disc battery in the esophagus (80.7%). Conclusion: FB in ENT is among the emergency conditions that require different diagnostic and treatment approaches based on anatomic localizations. Proper vision, adequate equipment and immobilization are important in the removal of ENT foreign bodies in children.

Opis:
Introduction: The nasal valve is the main regulator of airflow in the nose. Consequently, the collapse of the nasal valve has a significant impact on nasal obstruction and hence quality-of-life of patients. Several nasal valve rhinoplasty techniques are being used, from cartilage grafts to endonasal resection of the upper lateral cartilage. We describe a new endonasal approach to nasal valve rhinoplasty, the Triangular Technique, and assess its efficacy and complication rate over ten years. Materials and Methods: A retrospective study of patients who underwent nasal valve rhinoplasty at three regional hospitals from Jan 2004 to May 2014 was conducted. Subjective reports were used to assess the improvement of nasal obstruction. A total of 24 patients were included. Results: Three months postoperatively, 19 patients reported improvement in nasal obstruction. Four patients required revision surgery. Two of these 4 patients had substantial symptom resolution post revision surgery. Ten patients were followed up for more than 5 years (range: 5.8 to 10.3 years), 9 of who reported continued satisfaction and none or minimal nasal obstruction after nasal valve rhinoplasty compared to before surgery. There were no reported complications. Discussion: The Triangular Technique is a straightforward endonasal technique to address collapsed nasal valves with minimal associated co-morbidities.

Opis:
The ricochet behaviour of the air–water trans-media vehicle (AWTMV) during water-entry crossing was experimentally investigated. Three types of small-scale AWTMV including cone, ogive, and flat nose were used in the test. The underwater trajectory, velocity, and inclination angle of projectiles during the ricochet process were obtained using a high-speed camera. The angle change of the AWTMV and the ratio of the residual velocity are introduced. Based on this result, the relationship between the ricochet responses and initial conditions was derived. The results of this study show that (1) a small incident angle and great velocity make the occurrence of ricochet behaviour easier, (2) the stability of the trajectory of projectiles with cone, ogive, and flat nose weakened in turn at the same initial conditions, (3) the angle change and the ratio of the residual velocity are linear functions of the incident angle and velocity.

Opis:
To improve the screw machining accuracy in modern air compressors. This paper investigates three main issues during the development process for cycloid screw machining methods on five-axis CNC machine tools with high precision and efficiency. First, the theoretical basis of cycloid screw surface shaping and derivative of the final profile equation is established. Then, modeling the center trajectory and feed rate according to the cycloid screw profile is given. Next is the experimental setup and simulation of the cycloid screw machining process and discussions. The obtained surface quality prediction parameters are close to the actual measured value, which can be used as a reference model for five-axis CNC milling technology processes. All experimental results obtained by the proposed mathematical model show that a surface with good surface quality is created, meeting the requirements for surface quality. The main work can be used as references for engineers and technicians in practice.

Opis:
Rhinophyma stanowi zaawansowaną postać trądziku różowatego. Guzowaty przerost nosa zewnętrznego jest schorzeniem o wieloletnim, przewlekłym przebiegu. Sam trądzik różowaty, stosunkowo często występujący, spotykany jest głównie u kobiet. Natomiast zaawansowane zmiany o typie rhinophyma występują zwykle u mężczyzn w 5–6 dekadzie życia. Etiopatogeneza choroby jest wieloczynnikowa i nie została ostatecznie poznana. Wiadomo, że w początkowych etapach dochodzi do zaburzeń w mikrokrążeniu w obrębie nosa i przerostu gruczołów łojowych. W ciągu lat następuje powolny rozrost i włóknienie skóry i tkanki podskórnej w obrębie nosa, co prowadzi do powiększenia i deformacji nosa. Zmieniony chorobowo, rozrośnięty, o zapalnie zmienionej powierzchni nos stanowi defekt estetyczny chorego. Może być również przyczyną obturacji przewodów nosowych. W latach 1992–2013 w Klinicznym Oddziale Chirurgii Szczę- kowo-Twarzowej obserwowano 5 chorych z przerostem guzowatym nosa. Poniżej przedstawiono opis przypadku chorego, który w ostatnim czasie był leczony w tut. Oddziale.
Rhinophyma is a late manifestation of rosacea. Nodular hypertrophy of the external nose is a chronic disease lasting for many years. Rosacea itself is a frequent disease most common among women, yet its manifestation resulting in rhinophyma is typical for men in their 50s and 60s. The etiopathogenesis of rosacea is complex and not yet investigated thoroughly. Early stages are characterized with disruption of microcirculation in the nose and hypertrophy of sebaceous glands. Over the years skin and subcutaneous tissues proliferate and become firous leading to enlargement and malformation of the nose. Lesions pose not only a cosmetic defect, but may also cause obstruction to the nasal passage. Between 1992 and 2013 fie patients who presented with rhinophyma were treated at the Clinical Department of Maxillo-Facial Surgery of Provincial Specialist Hospital in Rzeszów. A case study of a patient who was recently treated at the clinic is presented below.

Investigations were performed to examine the possibility of using an electronic nose to monitor development of fungal microflora during the first eighteen days of rapeseed storage. The Cyranose 320 device manufactured by Sensigent was used to analyse volatile organic compounds. Each sample of infected material was divided into three parts and the degree of spoilage was measured in three ways: analysis of colony forming units, determination of ergosterol content, and measurement of volatile organic compounds with the e-nose. Principal component analysis was performed on the generated patterns of signals and six groups of different spoilage levels were isolated. An analysis of sensorgrams for a few sensors with a strong signal for each group of rapeseed spoilage was performed. The ratio of the association time to the steady state was calculated. This ratio was different for the low level and the highest level of ergosterol and colony forming units. The results have shown that the e-nose can be a useful tool for quick estimation of the degree of rapeseed spoilage.

Opis:
Preface: angiomatous nasal type polyps (SAP ‒ sinonasal angiomatous polyp) are benign lesions. The clinical and radiological picture of SAP may suggest other diseases of the nose and paranasal sinuses. Diagnostic imaging is based on computed tomography and magnetic resonance. SAP treatment involves their surgical removal. A case report: he aim of the study is to present diagnostic and therapeutic difficulties in a 17-year-old female patient with an inflammatory polyposis of the angiomatous of the paranasal sinuses. The course of disease, diagnostic difficulties and its treatment are presented. No complications were observed during hospitalization and in the postoperative period. Summary: SAP is one of the types of nasal polyps characterized in the histological picture of vascular proliferation with the presence of blood clots. Accurate diagnostic and histological diagnostics allow to determine the final diagnosis and differentiation of SAP with nasal and sinus hyperplasia.
Wstęp: polipy nosa z rodzaju angiomatous (SAP ‒ sinonasal angiomatous polyp) są zmianami łagodnymi występującymi niezwykle rzadko. Obraz kliniczny i radiologiczny SAP może sugerować inne schorzenia nosa i zatok przynosowych. Diagnostyka obrazowa oparta jest na tomografii komputerowej i rezonansie magnetycznym. Leczenie SAP polega na ich chirurgicznym usunięciu. Opis przypadku: celem pracy jest przedstawienie trudności diagnostycznych i terapeutycznych u 17-letniej pacjentki z polipem zapalnym z rodzaju angiomatous zatok przynosowych. Przedstawiono przebieg choroby, trudności diagnostyczne i leczenie. Okres pooperacyjny oraz hospitalizacji był niepowikłany. Podsumowanie: SAP jest jednym z typów polipów nosa cechujących się w obrazie histologicznym proliferacją naczyń krwionośnych z obecnością w nich zakrzepów. Dokładna diagnostyka obrazowa i histologiczna pozwala na ustalenie ostatecznego rozpoznania i różnicowanie SAP z procesami rozrostowymi nosa i zatok.

The paper analyses the distorted data of an electronic nose in recognizing the gasoline bio-based additives. Different tools of data mining, such as the methods of data clustering, principal component analysis, wavelet transformation, support vector machine and random forest of decision trees are applied. A special stress is put on the robustness of signal processing systems to the noise distorting the registered sensor signals. A special denoising procedure based on application of discrete wavelet transformation has been proposed. This procedure enables to reduce the error rate of recognition in a significant way. The numerical results of experiments devoted to the recognition of different blends of gasoline have shown the superiority of support vector machine in a noisy environment of measurement.

Opis:
At present, "healthy eating" is gaining in popularity. Many people associate this term with eating plenty of vegetables and fruits. The basic elements influencing the selection of fruit are their appearance and smell. Of course, their origin and impact on human health are also very important. In recent years, exotic fruits have become increasingly accessible, making them gaining popularity, even among Poles. You can also meet plants created by crossing two varieties or species - so-called hybrids. They arise as a result of intersection of inbred lines created by multiple self-pollination of beneficial individuals. Although it is known that many of the hybrids created so far, With higher crop yields and better pro-health properties, these plants have not yet been thoroughly investigated. The purpose of the research was to compare the volatile fraction of hybrid fruit with the fruits which they came from. Thanks to such comparison, it was possible to classify fruits in terms of their quality, freshness and suitability for consumption. The chemical compounds that occur in the volatile fruit fraction in humans produce in people the aroma characteristic of each of them. By observing differences and similarities, it is possible to distinguish between them. To carry out the experiment, a comprehensive two-dimensional gas chromatography technique coupled with a mass spectrometer with time of flight mass spectrometer was used. In addition, samples were analyzed using an electronic nose, which uses ultrasonic gas chromatography.
