Introduction. The article is devoted to the consideration of lexical units that verbalize the BIOTECHNOLOGY concept in English. The relevance of the study lies in the need to specify the data on the verbalization of the BIOTECHNOLOGY concept by means of the English language, as consideration of the specifics of verbalization of this concept has not been given sufficient attention. The purpose of the article is determining the features of verbalization of the concept of BIOTECHNOLOGY / BIOTECHNOLOGY in the terminological system of the English language. Materials and methods of research. The material for the study was dictionary articles from English-language specialized, philological dictionaries and encyclopedic reference books. The methods of our study are definition, conceptual and frame analyzes. Results of the research. The significance of the "concept" as a basic concept of cognitive linguistics is revealed, the scientific concept is considered, which is the most important means of formation and development of a certain scientific branch. The main function of the scientific concept is the representation of the most relevant for science or scientific paradigm knowledge, experience, meanings, associations and scientific concepts. The evolution of the concept of "biotechnology" is considered. In order to establish the main verbalizers of the concept of BIOTECHNOLOGY in English, the dictionary articles of explanatory and encyclopedic dictionaries were used. At present, there are many interpretations of the concept of "biotechnology", but in general they all come down to one thing: in the traditional sense, biotechnology is an interdisciplinary field that emerged at the intersection of biological, chemical and technical sciences; is the use of living organisms and biological processes in industrial production. Understanding the concept of biotechnology as a "set of methods and techniques for obtaining useful products and phenomena with the help of biological agents" gives grounds to distinguish the following frames of the concept of BIOTECHNOLOGY: biological object, raw material, biotechnological product, technologies, processes and devices. Verbalization of selected frames takes place at the lexical and grammatical levels in the terminological system of the English language. Сonclusions. Thus, the scientific concept of BIOTECHNOLOGY / BIOTECHNOLOGY is the most important means of forming and developing the biotechnological scientific field. The researched concept consists of the following frames: biological object, raw materials, biotechnological product, technologies, processes and devices. Verbalization of selected frames takes place at the lexical and grammatical levels in the terminological system of the English language. Lexical verbalization of the concept BIOTECHNOLOGY involves the use of lexical units that nominate selected frames. At the grammatical level, the verbalization of the BIOTECHNOLOGY occurs through the use of terms of different structure: simple, complex and multicomponent.

Ternary Intermetallic Compound

The galvannealed steel sheets have received ever increased attention because of their excellent post-painting corrosion resistance and good weldability. However, its powdering and flaking tendency during press forming processes strongly impairs its performance. In order to optimize the properties of galvanneal coatings, it is critical to control the reaction rate between solid iron and molten zinc.In commercial galvannealing line, aluminum is added to zinc bath to retard the diffusion rate between iron and zinc by the formation of a thin layer of Al intermetallic compound on the surface of steel at initial hot-dip galvanizing. However, the form of this compound and its transformation are still speculated. In this paper, we report the direct observations of this compound and its transformation.The specimens were prepared in a hot-dip simulator in which the steel was galvanized in the zinc bath containing 0.14 wt% of Al at a temperature of 480 °C for 5 seconds and was quenched by liquid nitrogen.

The content and structure of mental representation of economic crises were studied and the flexibility of the structure in different social contexts was tested. Italian and Swiss samples (Total N = 98) were compared with respect to their judgments as to how a series of concrete examples of events representing abstract indicators were relevant symptoms of economic crisis. Mental representations were derived using a cluster procedure. Results showed that the relevance of the indicators varied as a function of national context. The growth of unemployment was judged to be by far the most important symptom of an economic crisis but the Swiss sample judged bankruptcies as more symptomatic than Italians who considered inflation, raw material prices and external accounts to be more relevant. A different clustering structure was found for the two samples: the locations of unemployment and gross domestic production indicators were the main differences in representations.

This article presents the rationale and methodology for developing an intrinsically safe device, namely, a hydrostatic fiber optic sensor with a position-sensitive detector for monitoring the level of oil products in large-capacity tanks at oil depots and during pumping in a raw material warehouses. This device suitable for continuous monitoring of the liquid level, based on the measurement of a hydrostatic column of liquid with automatic offset of changes in the density of the liquid. Offset is carried out by means of a displacer (a fully submerged float), inside which a housing with a position-sensitive detector (PSD) is integrated. Theoretical validation of the bellows suspension usage for a displacer is given. During filling a container with a liquid whose level is measured, liquid bellows, the movement of which is recorded by an optical triangulation sensor using the reflected infrared ray incident on the bottom of the bellows. The principle of the triangulation sensor operation is based on the geometric properties of the triangles. The pulses of infrared radiation come through a fiber optic cable. In order to measure the movement of the surface (the bottom of the bellows) by measuring the movement of the reflected beam, a position-sensitive detector is used, which is located in a remote controller. In this device for the intrinsic safety problem solution, optical inputs of a fiber optic flat cable are located in the active zone of the sensor, which is connected to the optical inputs of a position-sensitive detector, operated on the principles of photoelectric effect. The light spot moving along the sensitive zone and converted by the detector into a one-dimensional signal proportional to the distance to the object. hydrostatically applies pressure over the entire effective area of the measuring

Because of the almost-instant connection with the welfare and well-being of individuals, pharmaceutical industry stands prominently as a very important factor for the improvement and progress of a healthy productive nation. These days, pharmaceutical industry thrives as one of the largest and exponentially expanding global industries. Nonetheless, millions of people in low income developing countries, have to suffer from the fatal consequences of the inaccessibility and non-availability of essential drugs. This is also happening in Yemen, where the pharmaceutical manufacturers sector have to face up to many challenges. The Yemen Drug Company (YEDCO) was founded in 1964 by the Yemeni government as it collaborated with private investors. It was endorsed as a company with the expertise in the medicinal drug marketing. YEDCO started its work by taking in drugs from foreign companies and then locally marketing and distributing them. In 1982, YEDCO built the first medicinal factory for drugs in Sana’a. Since then, seven companies were set up to manufacture medicines in Yemen. The expanding population has led to the need to have more pharmaceutical products. It may be understandable that pharmaceutical manufacturer companies are also hit by the political crisis in the country. Inadequate amount of fuel and raw material as well as low security status were some of the underlying factors behind these ill-effects in Yemen. Imported drugs make up about nearly 90% % of the pharmaceutical market compared to 10% drugs from the domestic market. This situation has led to an additional burden being shouldered by the national economy, where Yemen spends about US$263 million annually on pharmaceutical drugs, in reference to the national Supreme Drugs Authority. Although there is a very quick growth in the population and drugs consumption, the pharmaceutical industry has not been very active, where global pharmaceutical products play their role dominantly on the domestic market. The pharmaceutical production necessitates skilled human resources like university graduates. By contrast, the government and the private sector should also motivate the pharmaceutical industry and make use of the local employment
