The importance of vocabulary in the learning of EFL has been an indisputable matter in ELT. The inclusion of vocabulary in ELT materials is often accompanied with questions such as what type of vocabulary and how many words to be taught for students in diverse ELT contexts. Hence, evaluating the kinds of vocabulary in ELT materials is similarly important. This study demonstrates a considerably unconventional corpus -informed materials evaluation to assess the suitability of the vocabulary content of ELT course books taught at the State Islamic Institute in Manado with its ESP context. Four ELT course books taught at the four schools of the State Islamic Institute were analysed using the corpus-based methods. A special software designed for corpus linguistics studies called e Antwordprofiler was used to count the coverage/frequency of occurrence of three types of Nation’ vocabulary classification. The results showed that the examined course books contain sufficient coverage of English high frequency words as required by theory that they contain a total coverage of 84.14 % of high frequency English word enlisted in the General Service List (GSL). However, in terms of the coverage of academic and technical vocabulary, these course books content were still considered under the theoretically acceptable coverage of at least 12,4 % and 5 % respectively. It is recommended that for ELT course books that are used in ESP teaching such as in a field-specific Islamic studies programs, the course books should fulfil the minimum coverage threshold of high frequency, academic and technical vocabulary.

This study compared the lexical coverage provided by four wordlists [West’s (1953) General Service List (GSL), Nation’s (2006) most frequent 2,000 British National Corpus word families (BNC2000), Nation’s (2012) most frequent 2,000 British National Corpus and Corpus of Contemporary American-English word families (BNC/COCA2000), and Brezina and Gablasova’s (2015) New-GSL list] in 18 corpora. The comparison revealed that the headwords in the BNC/COCA2000 tended to provide the greatest average coverage. However, when the coverage of the most frequent 1,000, 1,500, and 1,996 headwords in the lists was compared, the New-GSL provided the highest coverage. The GSL had the worst performance using both criteria. Pedagogical and methodological implications related to second language (L2) vocabulary learning and teaching are discussed in detail.

The article highlights the results of research carried out in 2019-2020 to study the reasons for the drying out of the stems of black currant (Ribes nigrum L.), red currant (Ribes rubrum L.) and golden currant (Ribes aureum L.). As a result of research, the fungus Sphaeropsis malorum Peck. in the first in Russia it was revealed from the drying stems of three types of black currants, red currants and golden currants. This  pathogen inhabited currant stems together with fungi from the genus Cytospora spp., causative agents of stem drying. On red currants, it was established that S. malorum was the main causative agent of branch drying, as indicated by the high frequency of occurrence (75.0-83.3 %) of this fungus on the affected stems, compared with species from the genus Cytospora spp. (16.7-33.3 %) and Phomopsis ribesia (25.0 %). Due to the fact that the cultivation of currants in the immediate vicinity of apple and pear trees leads to infection of plants with the fungus S. malorum, it is necessary to avoid planting currants in the vicinity of fruit-bearing seed gardens.

The high frequency of occurrence of candidiasis as well as high mortality of patients with immunosuppression cause a tendency toward better understanding of Candida albicans species virulence factors and developing sensitive and specific diagnostic methods, and appropriate strategies of candidiasis treatment. In recent decades the incidence of fungal infections has alarming increases because of advanced medical treatments. In this study was analyzed possible ultrastructural changes of the species C. albicans cells following treatment with sodium diclofenac at various concentrations. Following treatment of C. albicans cells with sodium diclofenac 1 mM and 2 mM changes in the plasmalemma can be noticed, changes in the density of cell wall, disruption and necrotic appearance of the cytoplasm.

The investigation of the vascular microcirculation system is important for diagnosis, assessment of the severity and nature of pathological processes in human body, monitoring the effectiveness of treatment. Monitoring the state of microcirculation in impaired respiratory function of the nose helps to study the subtle mechanisms of regulation of vascular−tissue relations. To do this, there were used the biomicroscopic methods to study capillary blood flow, one of the most relevant and promising is optical capillaroscopy of the nail bed. This method makes it possible to identify at the evidence level the peculiarities of the functioning of the peripheral circulatory system by the state of the capillary system and to evaluate the effectiveness of treatment by the rheological properties of blood in hematological practice. There were examined 145 patients by means of computer capillaroscopy to study the rate of capillary circulation in the patients with pathology of intranasal structures and nasal breathing disorders. All patients underwent a complete clinical examination, routine instrumental examinations, and computer capillaroscopy using a video capillaroscope with a visual magnification of up to 550 times. The obtained images were stored and processed according to a special software. During the characterization of the capillaroscopic picture there were evaluated: pathological tortuosity, change in the caliber of arterioles and venules, disorganization of the capillary network, the number of functioning capillaries. Changes in the speed and nature of capillary blood flow (accelerated, slow, stasis) were observed. The optical capillaroscopy method allows not only to visually assess the condition of microvessels, but also to determine such an important parameter as blood circulation, actually, it can replace the study of laser Doppler. Such data will be important in the diagnosis of respiratory and olfactory disorders and the formation of adequate tactics for their treatment. Key words: microcirculation, microcirculatory tract, capillary circulation, nasal obstruction, nasal breathing disorders, pathology of intranasal structures, computer capillaroscopy.

Abstract: Aim Identify seasonal variations in the diet of juvenile living in the estuary of the Parnaíba River Delta. Methods Food items were identified through analysis of stomach contents, and later submitted to analysis by regular methods for Frequency of Occurrence (FO), Frequency Numerical (FN), Gravimetric Frequency (FW) and Relative Importance Index (IRI). Results Juvenile diet of Elops saurus that inhabit the lagoons in the Parnaíba delta was composed in order decreasing of importance by Osteichthyes (Teleostei), Insecta and Crustacea in addition to Polychaeta and Nematoda. It was also observed a high frequency of occurrence of fragments of plastics in the diet. In the rainy season, 17 items were recorded in the diet, whereas in the dry season only 7 items were present. Relative Importance Index showed high presence of the Teleostei fish (69.93%) on diet of E. saurus during the rainy season, whereas during the dry period the insects of the families Corixidae (43.25%) and Dysticidae (39.16%). Conclusions With the study it was possible to identify that juvenile are piscivorous in the rainy season when there is a higher availability of prey in the environment and insectivores in the dry season when it reduces the supply of food, indicating feeding flexibility to environmental alterations.

The paper presents the results of an experimental study aimed at assessing the correlation between the measurement of dynamic parameters (vibration, high-frequency vibration, and acoustic emission) and the analysis of friction mode and the state of lubrication of the contact surfaces of two gearboxes in the turbo-generator assembly (high-speed single-body steam turbine—gearbox—generator) with the transmission power of no more than 50 MW. The analysis confirmed the assumption of a significant correlation of the monitored high-frequency vibration signal with the unsatisfactory engagement of the gear teeth. Through vibration analysis, an increased level of the tooth vibration component and vibration multiples with increased acoustic emission were identified in gearbox operation. The gear oil of one of the gearboxes examined showed a loss of additive elements in the real operation of the contact surfaces of the teeth engagement. The trend analysis confirmed the complexity of the monitored transmission operation in terms of the friction mode and the influence of the oil quality on the state of the tooth flank microgeometry.
