THE ESSENCE OF COMMON METHODS OF TEACHING FOREIGN LANGUAGES

Today, knowledge of foreign languages is required to avoid barriers to communication between people around the world. Thus, learning foreign languages is relevant at almost any age.The purpose of this article is to consider the generally accepted methods and determine the effectiveness of each of them during training. To achieve fluency in a foreign language, it is necessary to divide foreign language communicative competence into a number of components and develop them both individually and in combination. Each of the models is a separate and independent method that can be used to improve certain components of foreign language communicative competence. The main components include: the development of speech, writing, reading, and the study of vocabulary. There is no single approach in the scientific literature to determine the structure of foreign language communicative competence, as the general form of this competence can be presented in a set of components such as linguistic, sociolinguistic and pragmatic competence. Therefore, it is not possible to dwell on a specific method as ideal for the formation of competence, as each of them has its disadvantages and advantages. The formation of foreign language communicative competence requires a long and careful study of the material offered by a teacher who uses a certain method.

Comparison of culture-dependent and culture-independent techniques in the detection of lactic acid bacteria biodiversity and dynamics throughout the ripening process: The case of Turkish artisanal Tulum cheese produced in the Anamur region

Our objective was to analyze the diversity of the microbiota over 180 d of ripening of eight batches of artisanal goatskin Tulum cheeses by culture-dependent and culture-independent (PCR-DGGE) methods. V3 region of the bacterial 16S rRNA gene was amplified with the PCR after direct DNA isolation from the cheese samples. Nine different species and five genera were determined by culturing, while 11 species were identified in the PCR-DGGE technique. This diversity revealed the uniqueness of artisanal cheese varieties. The dominant genera in all the cheese samples were composed of Enterococcus species. The culture-dependent method revealed five genera (Enterococcus,Bacillus,Lactococcus,Lactobacillus, Sphingomonas) while three genera (Enterococcus, Streptococcus, Lactococcus) were detected in the culture-independent method. It was concluded that combining the two methods is important for characterizing the whole microbiota of the Tulum cheese varieties produced in the Anamur region.

Intrastromal keratoplasty with intracorneal ring segments implantation as an independent method of visual rehabilitation in patients with keratoconus

Purpose. To assess the possibility of using intrastromal keratoplasty with intracorneal ring segments implantation as an independent technique to achieve visual rehabilitation in patients with keratoconus of the stages I and II. Material and methods. There were examined and operated 14 eyes (10 patients) with keratoconus of the stages I and II (classification by Izmailova SB, 2014). Patients were divided into two groups depending on the keratoconus stage. All patients underwent intrastromal keratoplasty with intracorneal ring segments implantation using the femtosecond technology. The on average follow-up was 5.7 months. Results. In the first group: the average UCVA value increased with from 0.31±0.21 to 0.81±0.31 (p<0.05); the BCVA increased from 0.89±0.08 to 0.94±0.10 (p>0.05); the spherical component of refraction decreased from 0.96±1.25 to 0.08±0.20 (p<0.05); the cylindrical component of refraction decreased from 4.25±1.73 to 0.50±1.22 (p<0.05). In the second group: UCVA increased from 0.51±0.40 to 0.61±0.28 (p<0.05); the BCVA increased from 0.70±0.17 to 0.81±0.26 (p>0.05); the spherical component of refraction decreased from 4.88±2,61±0.53±0.63 (p<0.05); the cylindrical component of refraction decreased from 2.69±1.65 to 1.41±1.02 (p<0.05). Conclusion. 1. After implantation of intracorneal ring segments, both in patients with I and in patients with the II stage of keratoconus, there was an increase in the UCVA and BCVA, as well as a significant reduction in maximal keratometry and coma, which provides the improving of the quality of vision. 2. In all cases the UCVA and BCVA that were obtained after the treatment reached a sufficiently high level to ensure the possibility of performing their professional functions, without resorting to additional surgical treatment techniques. That characterizes this method as an independent and sufficient to achieve high visual acuity in patients with I and II stages of keratoconus. Key words: keratoconus, corneal intrastromal segments, femtosecond laser, visual rehabilitation.

On the tuning of plateaus in atmospheric and oceanic ¹⁴C records to derive calendar chronologies of deep-sea cores and records of ¹⁴C marine reservoir age changes

We assess the methodology of the so-called 14C plateau tuning (PT) technique used to date marine sediment records and determine 14C marine reservoir ages (MRAs) as recently reviewed by Sarnthein et al. (2020). The main identified problems are linked to the assumption of constant MRA during 14C age plateaus; the lack of consideration of foraminifera abundance changes coupled to bioturbation that can create spurious plateaus in marine sediments; the assumption that plateaus have the same shapes and durations in atmospheric and oceanic records; the implication that atmospheric 14C / 12C peaked instantaneously from one plateau to the next; that the 14C plateaus represent 82 % of the total time spent between 14 000 and 29 000 cal yr BP, whereas during the remaining 18 % of the time, the radiocarbon clock was running almost 5 times faster than the radioactive decay; that the sparsity, combined with the level of analytical uncertainties and additional noise, in both atmospheric and marine data do not currently allow one to reliably or robustly identify plateaus (should they exist) beyond 15 000 cal yr BP; and that the determination and identification of plateaus in the deep-sea cores is reliant upon significant changes in sedimentation rate within those marine sediments which are, a priori, unknown and are not verified with an independent method. The concerns we raise are supported and strengthened with carbon cycle box model experiments and statistical simulations of pseudo-atmospheric and pseudo-marine records, allowing us to question the ability to identify and tune 14C age plateaus in the context of noisy and sparse data.
